The franchise's firstWorld Series appearance came in1944 when the Browns lost to theSt. Louis Cardinals. The Orioles went on to make six World Series appearances from 1966 to 1983, winning three in1966,1970, and1983. This era of the club featured several futureHall of Famers who would later be inducted representing the Orioles, such as third basemanBrooks Robinson, outfielderFrank Robinson, starting pitcherJim Palmer, first basemanEddie Murray, shortstopCal Ripken Jr., and managerEarl Weaver. The Orioles have won a total of ten division championships (1969, 1970, 1971, 1973, 1974, 1979, 1983, 1997, 2014, 2023), sevenpennants (1944 while in St. Louis, 1966, 1969, 1970, 1971, 1979, 1983), and fourwild card berths (1996, 2012, 2016, 2024). The franchise was the last charter member of the American League to win a pennant, and the last charter member to win a World Series.

After 14 consecutive losing seasons between 1998 and 2011, the team qualified for the postseason three times under managerBuck Showalter and general managerDan Duquette, including a division title and advancement to theAmerican League Championship Series for the first time in 17 years in2014.Four years later, the Orioles lost 115 games, the most in franchise history.^[6] The Orioles chose not to renew the expired contracts of Showalter and Duquette after the season, ending their respective tenures with Baltimore. The Orioles' current manager isBrandon Hyde, whileMike Elias serves as general manager and executive vice president. Two years after finishing 52–110 in 2021, the Orioles went 101–61 in 2023, en route to winning the AL East for the first time since 2014.

From 1901 through the end of 2024, the franchise's overall win–loss record is9,120–10,084–110 (.475). Since moving to Baltimore in 1954, the Orioles have an overall win–loss record of5,658–5,530–12 (.506) through the end of 2024.[7]

The Orioles franchise can trace its roots back to the originalMilwaukee Brewers of theWestern League (WL), beginning in 1894 when the league reorganized. The Brewers were still league members when the WL renamed itself theAmerican League (AL) in 1900. At the end of the 1900 season, the AL removed itself from baseball's National Agreement, the formal understanding between theNational League (NL) and the minor leagues, and declared itself a competing major league. During 1901, the first season the AL operated as a major league, the Brewers finished last among the league's eight teams.

In 1902, the team moved toSt. Louis and became the "Browns", named after the original name of the 1880s club now known as theCardinals. Although they usually fielded mediocre teams, they were very popular at the gate. In 1916, after years of prosperity at the gate,Robert Hedges sold the team toPhil Ball, who made a considerable effort to make the Browns competitive. However, Ball's tenure was marked by errors, including the firing ofBranch Rickey, which eventually benefited the Cardinals, who sharedSportsman's Park with the Browns.

The1944 season saw the Browns winning their only St. Louis-based American League pennant, becoming the last of the 16 teams that made up the major leagues from 1901 to 1960, to play in aWorld Series. In 1951,Bill Veeck purchased the Browns and introduced a series of promotions and wild antics. Veeck's efforts to drive the Cardinals out of St. Louis failed whenAnheuser-Busch purchased the Cardinals. Veeck attempted to move the Browns toMilwaukee and thenBaltimore, but both moves were initially blocked by other American League owners. Eventually, Veeck sold his stake to a group of Baltimore investors, and the team moved to Baltimore for the1954 season, renaming themselves the Baltimore Orioles. The name has a rich history in Baltimore, having been used by Baltimore baseball teams since the late 19th century. The Orioles' early years in Baltimore were marked by a gradual climb to respectability, leading to their firstWorld Series title in 1966. The Orioles enjoyed a period of sustained success from 1966 to 1983, winning three World Series titles and sixAmerican League pennants.

After the 1983 World Series win, the Orioles experienced a decline, culminating in the 1988 season where they lost the first 21 games. In 1989, the Orioles showed improvement with the "Why Not?" Orioles finishing second in the AL East. The opening ofOriole Park at Camden Yards in 1992 marked a new era, and the team returned to the playoffs in 1996 and 1997. However, the late 1990s and 2000s were characterized by losing seasons and rebuilding efforts. The Orioles saw a resurgence in the 2010s, making the playoffs in 2012, 2014, and 2016, withBuck Showalter as manager. The team struggled again towards the end of the decade, leading to a major rebuild. The 2020s have been marked by rebuilding efforts and developing young talent, aiming for future competitiveness.

In 2022, anticipated first-round pick catcherAdley Rutschman made his major-league debut in addition to rookie closerFélix Bautista. The Orioles finished the 2022 season with a 83–79 record, becoming the second team in MLB history to have a winning season only one year after losing 110 or more games.

On June 9, 2022, Louis Angelos sued his brother, Orioles chairman and CEO John P. Angelos, and mother Georgia Angelos in Baltimore County Circuit Court.^[9][10] Louis Angelos claims that their father intended for the brothers and their mother to share control of the team. The lawsuit states the elder Angelos collapsed in 2017 due to heart problems and established a trust with his wife and sons as co-trustees. Louis Angelos is seeking to have his brother and mother removed as co-trustees of the trust that controls the Orioles and removed as co-agents of Peter Angelos' power of attorney.

The suit claims Georgia Angelos wants to sell the team and an advisor attempted to negotiate a sale in 2020 but John Angelos vetoed a potential deal. The suit claims Angelos unilaterally fired long-time employees loyal to his father, including former center fielderBrady Anderson, the longtime special assistant to the executive vice president for baseball operations. The suit claims John Angelos transferred tens of millions of dollars' worth of property out of his father's law firm and into a limited liability company controlled by his personal attorney.^[9] In separate statements released by the team, Georgia and John Angelos refuted the claims.^[11][12] In the event of any sale, Major League Baseball has reportedly encouraged Cal Ripken Jr to be part of any incoming ownership group that may take control of the team.^[13]

In April 2023, the Orioles went 19–9, setting a franchise record for wins in the month of April.^[14] By August 2023, the Orioles, led by a core of first-and-second-year playersAdley Rutschman,Gunnar Henderson,Félix Bautista andKyle Bradish, were in first place in the division and described inThe Athletic as "young, fun and arguably the best story in baseball." However, the front office went under scrutiny when it was reported that play-by-play announcer Kevin Brown had been suspended indefinitely by the Orioles for his pregame remarks onMASN, the team-owned network, two weeks earlier. During a "seemingly benign" introduction to a game against theTampa Bay Rays, Brown observed that the team had not won a series atTropicana Field in the past several seasons. It was described inThe Athletic as a "petty" move by John Angelos, "the only person [in the organization] with enough power that no one dare question the validity of anything he says and does, no matter how foolish it is."^[15] Several broadcasters came to Brown's defense after the news broke.Gary Cohen said the team had "draped itself in utter humiliation" andMichael Kay said the suspension made "the Orioles look so small and insignificant and minor league."^[16] Brown returned to broadcasting for the team and stated in a public message that "recent media reports [had] mischaracterized my relationship with my adopted hometown Orioles" and that his relationship with the team was "wonderful".^[17]

In May 2023, following the team's new water-themed celebrations, Camden Yards created a Bird Bath splash zone in left field, where fans in one section had the opportunity get sprayed by the water hose-wielding "Mr. Splash" following an Orioles extra base hit.^[18]

The Orioles finished the 2023 season with a record of 101–61,^[19] winning theAmerican League East division for the first time since 2014, and claiming their first 100+ win season since 1980. On July 30, the pitching staff ofDean Kremer,Mike Baumann,Shintaro Fujinami,Danny Coulombe, andYennier Canó combined to set a franchise record for the most strikeouts in a 9-inning game against the Yankees.^[20] The 2023 pitching staff also broke the Orioles franchise record of single-season strikeouts on September 6.^[21] However, the team's successful season ended in the postseason American League Division Series, with the Orioles losing three straight games to the Texas Rangers.^[22] The series sweep was the first time since the 2022 season that the Orioles had been swept in a series.^[23]

ManagerBrandon Hyde was awarded 2023 AL Manager of the Year, and players Adley Rutschman and Gunnar Henderson both were awarded theSilver Slugger Award. Additionally, Henderson was voted unanimous ALRookie of the Year,^[24] marking the first time the team had a ROY winner sinceGregg Olson in 1989.

In January 2024, John Angelos reached a $1.7 billion deal to sell the Orioles to a group led byDavid Rubenstein, a Baltimore native and founder ofThe Carlyle Group. The group includes Cal Ripken, New York investment manager Michael Arougheti, former Baltimore mayorKurt Schmoke, businessmanMichael Bloomberg and NBA hall of famerGrant Hill. For tax reasons, the group would acquire 40% of the team with the Angelos family selling the remainder of Peter Angelos' stake after his death. The deal includes the Orioles' majority stake in MASN.^[25][26][27] Peter Angelos died aged 94 on March 23, 2024;^[28] his death occurred four days before the sale of the Orioles was finalized.^[29]

On August 1, 2024, the Orioles' majority ownership group led by private equity billionaire David Rubenstein took full control of the team, when a deal closed for the group to purchase the remainder of the organization.[1]

The Orioles' home uniform is white with the word "Orioles" written across the chest. The road uniform is gray with the word "Baltimore" written across the chest. This style, with noticeable changes in the script, striping and materials, has been worn for much of the team's history, but with a few exceptions:

• In 1954, 1989–94 (road) and 1995–2003 (home), the scripted word "Orioles" and block letters are rendered in black with orange trim. The 1995–2003 style featured orange numbers in front but black letters in the back.
• From 1963 to 1965, the home uniforms featured "Orioles" in block lettering instead of the more familiar cursive script style. It was also rendered in black with orange trim.
• The underline below the word "Orioles" disappeared from 1966 to 1988.
• Road uniforms bore the team name from 1954 to 1955 and from 1973 to 2008.
• Extra white trim was added to the road and alternate uniforms from 1995 to 2000.
• Sleeveless home alternate uniforms were used in the 1968 and 1969 seasons.
• Player names were added to the uniforms in 1966, but the home uniforms originally featured black block letters. It would not match the road uniform lettering until 1971, which were orange with black trim.

A long campaign of several decades was waged by numerous fans and sportswriters to return the name of the city to the "away" jerseys which was used since the 1950s and had been formerly dropped during the 1970s era ofEdward Bennett Williams when the ownership was continuing to market the team also to fans in the nation's capital region after the moving of the formerWashington Senators in 1971. After several decades, approximately 20% of the team's attendance came from the metro Washington area.^{[citation needed]}

In 2013,ESPN ran a "Battle of the Uniforms" contest between all 30 Major League clubs. Despite using a ranking system that had the Orioles as a #13 seed, the Birds beat the #1 seedCardinals in the championship round.^[31]

The Orioles' cap design have alternated between the team's iconic "cartoon bird" logo and the full-bodied bird logo. Initially, the caps had the full-bodied bird logo between 1954 and 1965, alternating between an all-black cap and an orange-brimmed black cap. They also wore a black cap with an orange block-letter "B" for part of the 1963 season. The "cartoon bird" was first used in 1966, and with minor tweaks, was prominently featured on the team's caps until 1988. Initially, the Orioles kept the orange-brimmed black cap with the "cartoon bird" but switched to a white-paneled black cap with orange brim in 1975. Also that same year, they wore orange-paneled black caps to pair with the orange alternates, but these lasted only two seasons.

In 1989, the full-bodied bird logo returned along with the all-black cap, with a few tweaks along the way. Initially the cap was used regardless of home or road games, but in 2002 the caps were worn only on the road until 2008. An orange-brimmed variety was also introduced in 1995. Initially exclusive to the team's black uniforms, this style became the home cap in 2002 and became the team's regular cap (home or away) from 2009 to 2011.

In 2012, the Orioles brought back a modernized version of the "cartoon bird" along with the white-paneled and orange-brimmed black cap for home games and the orange-brimmed black cap for road games.

Analternate uniform is black with the word "Orioles" written across the chest. They first wore black uniforms in the 1993 season and continue to do so since; the current style with the letters lacking additional trim was first used in 2000. The Orioles wear their black alternate jerseys for Friday night games with the alternate "O's" cap (first introduced in 2005), whether at home or on the road; the regular batting helmet is still used with this uniform. In 2017, the Orioles began to use their batting practice caps for select games with the black uniforms. The aforementioned caps resemble their regular road caps save for the black bill. Occasionally, the Orioles would also wear the black alternates on other days of the week, often pairing them with the home or road "cartoon bird" caps. After the "City Connect" uniforms became the team's Friday home uniform (see below), the black alternates were only used on Friday road games and on home games depending on the preference of the starting pitcher.

The Orioles also wore orange alternate uniforms at various points in their history. The orange alternates were first used in the 1971 season and were paired with orange pants, but these lasted only two seasons. The second orange uniform, which was a pullover style, was worn from 1975 to 1987, but were not worn at all in the 1983, 1985 and 1986 seasons. A third orange uniform was used from 1988 to 1992, returning to the button-down style. In 2012, the Orioles brought back the orange uniforms as a second alternate uniform; the team currently wears them on Saturdays at home or on the road, though they've also worn them on other days of the week either due to pitcher's preference or a previously postponed contest. For 2025, the Orioles brought back the all-orange alternate for select games, while keeping the orange uniform/white pants option for a few other games.^[32]

In 2023, the Orioles introduced aCity Connect uniform, inspired by the art and culture of Baltimore and its neighborhoods. The uniform is mostly black base from the jersey to pants. Across the chest, it features the city name "BALTIMORE" in white lettering, and on the collar and sleeves features a small batch of colors and shapes, representing theneighborhoods of Baltimore. The cap, which is also on a black base, features an italic white "B". In 2024, the City Connect uniform was worn with the home white pants for select games.^[33]

TheOrioles announced its first-ever jersey sponsorship deal withT. Rowe Price on June 10, 2024. A circular dark blue,aqua and white sleeve patch with theinvestment management firm'sbighorn sheep logo debuted in ahome game against theAtlanta Braves the following night on June 11.^[34][35]

In Baltimore, Orioles radio broadcasts can be heard onWBAL-AM andWIYY, both owned byHearst Television.Geoff Arnold,Melanie Newman, Brett Hollander, Scott Garceau andKevin Brown alternate asplay-by-play announcers. WBAL feeds the games to anetwork of 36 stations, covering Washington, D.C., and all or portions of Maryland, Pennsylvania, Delaware, Virginia, West Virginia, and North Carolina.

This is WBAL's fourth stint as the Orioles flagship. WBAL has carried Orioles games for most of the team's time in Baltimore. Prior to WBAL and WIYY, Orioles games were broadcast locally onWJZ-FM from 2015 to 2021. WJZ had earlier carried broadcasts from 2007 to 2010.

Six former Orioles franchise radio announcers have received the Hall of Fame'sFord C. Frick Award for excellence in broadcasting:Chuck Thompson (who was also the voice of the old NFLBaltimore Colts);Jon Miller (now with theSan Francisco Giants);Ernie Harwell,Herb Carneal;Bob Murphy andHarry Caray (as a St. Louis Browns announcer in the 1940s^[36]).

Other former Baltimore announcers includeJosh Lewin (currently withNew York Mets),Bill O'Donnell,Tom Marr, Scott Garceau (returned in 2020 season),Mel Proctor,Michael Reghi, former major league catcherBuck Martinez (nowToronto Blue Jays play-by-play), Joe Angel and former Oriole players including Brooks Robinson, pitcherMike Flanagan and outfielderJohn Lowenstein. In 1991, the Orioles experimented with longtime TV writer/producerKen Levine as a play-by-play broadcaster. Levine was best noted for his work on TV shows such asCheers andM*A*S*H, but lasted only one season in the Orioles broadcast booth.

MASN, co-owned by the Orioles and the Washington Nationals, is the team's exclusive television broadcaster. MASN airs almost the entire slate of regular season games. Some exceptions includeSaturday games on eitherFox (via its Baltimore affiliate,WBFF) orFox Sports 1, orSunday Night Baseball onESPN. Many MASN telecasts in conflict with Nationals' game telecasts air on an alternate MASN2 feed.

Veteran sportscasterGary Thorne served as lead television announcer from 2007 to 2019, withJim Hunter as his backup along with Hall of Fame member and former Orioles pitcherJim Palmer and former Oriole infielderMike Bordick as color analysts, who almost always work separately. In 2020, Thorne and Palmer were removed from the television booth due toCOVID-19 concerns and replaced with Scott Garceau. In 2021, MASN let go Thorne, Hunter, analysts Mike Bordick andRick Dempsey, and studio host Tom Davis, and addedBen McDonald as a secondary analyst.^[37][38][39] Starting in 2022, Kevin Brown became the primary TV play-by-play announcer, with Garceau, Arnold or Newman the backups.^[40]

The Orioles severed their ties with Comcast SportsNet Mid-Atlantic (nowNBC Sports Washington) at the end of the 2006 season in favor of MASN, a joint venture with theWashington Nationals. It had been the Orioles' cable partner since 1984, when it was known as Home Team Sports. The Orioles and the Washington Nationals have been in a dispute since the early 2010s, MASN is owned by both teams with the Orioles holding an 80% stake. The dispute which is ongoing as of October 2020 contends that the Nationals deserves a greater fee from MASN due to the team's recent success and market growth. When fees paid to each team were first negotiated, both teams were paid the same fees.^[41]

WJZ-TV was the Orioles' broadcast TV home, completing its latest stint from 1994 through 2017. Since MASN acquired rights in 2007, its coverage wassimulcast on WJZ-TV under the branding "MASN on WJZ 13". MASN elected not to syndicate any Orioles or Washington Nationals games to broadcast television for the 2018 season, marking the first time since the Orioles' arrival that their games are not on local broadcast television.^[42]

Previously, WJZ-TV carried the team from their arrival in Baltimore in 1954 through 1978. In the first four seasons, WJZ-TV shared coverage with Baltimore's other two stations,WMAR-TV andWBAL-TV. The games moved to WMAR from 1979 through 1993 before returning to WJZ-TV. From 1994 to 2009, some Orioles games aired onWNUV.

Since its introduction at games by the "Roar from 34", led byWild Bill Hagy and others, in the late 1970s, it has been a tradition at Orioles games for fans to yell out the "Oh" in the line "Oh, say does that Star-Spangled Banner yet wave" in "The Star-Spangled Banner".^[43] "The Star-Spangled Banner" has special meaning to Baltimore historically, as it was written during theBattle of Baltimore in theWar of 1812 byFrancis Scott Key, a Baltimorean.

The tradition is often carried out at other sporting events, both professional and amateur, and even sometimes at non-sporting events where the anthem is played, throughout theBaltimore/Washington area and beyond. Fans inNorfolk, Virginia, chanted "O!" even before theTides became an Orioles affiliate. The practice caught some attention in the spring of 2005, when fans performed the "O!" cry atWashington Nationals games atRFK Stadium. The "O!" chant is also common at sporting events for the variousMaryland Terrapins teams at theUniversity of Maryland, College Park. AtCal Ripken Jr.'s induction into theNational Baseball Hall of Fame, the crowd, composed mostly of Orioles fans, carried out the "O!" tradition duringTony Gwynn's daughter's rendition of "The Star-Spangled Banner". Additionally, a faint but audible "O!" could be heard on the television broadcast ofBarack Obama's pre-inaugural visit to Baltimore as the national anthem played before his entrance. A resounding "O!" bellowed from the nearly 30,000 Ravens fans who attended the November 21, 2010, away game at theCarolina Panthers'Bank of America Stadium in Charlotte, North Carolina.^[44] A similar loud "O!" was heard from fans attendingSuper Bowl XLVII between theBaltimore Ravens and theSan Francisco 49ers.^[45] The "O!" chant was also heard during the2016 Summer Olympics inRio de Janeiro, Brazil, when Baltimore nativeMichael Phelps received his gold medal for the4 × 200 m freestyle on August 9, 2016.^[46]

In recent years, when the Orioles host theToronto Blue Jays, fans have begun to shout out the multiple instances of the word "O" in "O Canada".Washington Capitals fans will do the same when they play one of the NHL's Canadian teams.

It has been an Orioles tradition since 1975 to playJohn Denver's "Thank God I'm a Country Boy" during theseventh-inning stretch.

In the edition of July 5, 2007, of Baltimore's weekly sports publicationPress Box, an article by Mike Gibbons covered the apocryphal details of how this tradition came to be.^[47] During "Thank God I'm a Country Boy", Charlie Zill, then an usher, would put on overalls, a straw hat, and false teeth and dance around the club level section (244) that he tended to. He also has an orange violin that spins for the fiddle solos. He went by the name Zillbilly and had done the skit from the 1999 season until shortly before he died in early 2013. Of course, that does nothing to explain why the Orioles' Audio staff began playing the song during every game's seventh inning stretch beginning in August 1975.

In reality, the song was tremendously successful nationwide, topping the Billboard Top 100 for one week in 1975, and was played in stadiums across the country. The Orioles were chasing the Red Sox for the American League East Division title and incorporated numerous "good luck charms." After an inspiring comeback win, Oriole staff began playing this song at the seventh inning stretch of every home game as one of the good-luck charms, beginning in August.

During a nationally televised game on September 20, 1997, Denver himself danced to the song atop the Orioles' dugout, one of his final public appearances before dying in a plane crash three weeks later.^[48]

Songs from notable games in the team's history include "One Moment in Time" for Cal Ripken's record-breaking game in 1995, as well as the theme fromPearl Harbor, "There You'll Be" byFaith Hill, during his final game in 2001. The theme fromField of Dreams was played at the last game at Memorial Stadium in 1991, and the song "Magic to Do" from the stage musicalPippin was used that season to commemorate "Orioles Magic" on 33rd Street. During the Orioles' heyday in the 1970s, a club song, appropriately titled "Orioles Magic (Feel It Happen)", was composed by Walt Woodward,^[49] and played when the team ran out until Opening Day of 2008. Since then, the song (a favorite among all fans, who appreciated its references toWild Bill Hagy andEarl Weaver) is played (along with a video featuring several Orioles stars performing the song) only after wins. In the 2010s, "Seven Nation Army" was often played as a hype song while the fans chant the signature bass riff as a rally cry during key moments of a game or after a walk-off hit. In the 2023 season, closer Felix Bautista would come out of the bullpen to the ominous whistle ofThe Wire characterOmar Little.^[50]

During the Orioles' final homestand of the season, it is a tradition to display a replica of the 15-star, 15-stripeAmerican flag at Camden Yards. Prior to 1992, the 15-star, 15-stripe flag flew from Memorial Stadium's center-field flagpole in place of the 50-star, 13-stripe flag during the final homestand. Since the move to Camden Yards, the former flag has been displayed on the batters' eye. During the Orioles' final home game of the season,The United States Army Field Band fromFort Meade performs theNational Anthem prior to the start of the game. The Band has also played the National Anthem at the finales of threeWorld Series in which the Orioles played:1970,1971 and1979. They are introduced as the "First Army Band" during the pregame ceremonies.

For 23 years,Rex Barney was thePA announcer for the Orioles. His voice became a fixture of both Memorial Stadium and Camden Yards, and his expression "Give that fan a contract", uttered whenever a fan caught afoul ball, was one of his trademarks – the other being his distinct "Thank Yooooou ..." following every announcement. (He was also known on occasion to say "Give that fan an error" after a dropped foul ball.) Barney died on August 12, 1997, and in his honor that night's game at Camden Yards against the Oakland Athletics was held without a public–address announcer.^[51]

Barney was replaced as Camden Yards' PA Announcer by Dave McGowan, who held the position from 1998 to 2011, after Chris Ely finished out the 1997 season.

Lifelong Orioles fan and formerMLB Fan Cave resident Ryan Wagner soon took over as the PA announcer. He was chosen out of a field of more than 670 applicants in the 2011–12 offseason. He held the job from 2012 to 2020. He was dismissed just hours before the team's 2021 home opener, reportedly because of his conduct onTwitter.^[52][53]

Adrienne Roberson, at the time the public address announcer for theBowie Baysox and Wagner's primary substitute, has been the team's announcer from 2021 onward.^[54] She became the second woman to be named an MLB team's primary PA announcer, followingRenel Brooks-Moon of theSan Francisco Giants.

Of the eight original American League teams, the Orioles were the last of the eight to win theWorld Series, doing so in1966 with its four–game sweep of the heavily favoredLos Angeles Dodgers. When the Orioles were the St. Louis Browns, they played in only one World Series, the1944 matchup against their Sportsman's Park tenants, theCardinals. The Orioles won the first-everAmerican League Championship Series in 1969, and in 2012 the Orioles beat the Texas Rangers in the inaugural American LeagueWild Card game, where for the first time two Wild Card teams faced each other during postseason play.
