This is a list ofMajor League Baseball (MLB) franchisepostseason andWorld Seriesstreaks. The list includes only the modern World Series between theAmerican League (AL) and theNational League (NL), not the various 19th-century championship series.
The Atlanta Braves have the longest postseason streak in MLB history, at 14 consecutive non-strike affected postseasons.
Overall the most successful postseason team in MLB history is theNew York Yankees, who have achieved three of the four instances of a franchise winning more than two World Series championships in a row (one streak each of durations 3, 4, and 5 seasons) and five of the six instances of a franchise winning the leaguepennant (i.e., an appearance in the World Series) more than three times in a row (three streaks of 4 seasons and two streaks of 5 seasons). The only other franchises to achieve these milestones are theOakland Athletics, who won three consecutive championships from 1972 to 1974, and theNew York Giants, who won four consecutive pennants from 1921 to 1924. The Yankees also achieved a remarkable run of appearing in 15 of the 18 World Series from 1947 to 1964.
Beginning in 1969, MLB split into four divisions, and the winners of each competed in theLeague Championship Series, with the winners advancing to the World Series. When a multi-tier playoff system was implemented in 1995, the LCS remained the series that determined the pennant-winner. The longest streak of consecutive LCS appearances belongs to theAtlanta Braves with eight in a row from 1991 to 1999 (not counting 1994, whenthere were no playoffs).
Further expansion of the postseason began in 1995, with eight teams entering the playoffs each year (further expanded to ten teams in 2012 and twelve in 2022). In this era, the Braves entered the postseason 14 consecutive years from 1991 to 2005 (again not counting 1994), while the Yankees had a streak of 13 appearances from 1995 to 2007. TheLos Angeles Dodgers (2013–2025) have an ongoing streak of 13 seasons.
The Yankees have achieved one streak each of three, four, and five championships in a row, and the Athletics have achieved a streak of three in a row. Back-to-back championships have been achieved an additional eleven times.

The Braves appeared in every LCS held from 1991 to 1999, which is eight in a row, winning five league pennants and oneWorld Series championship during that time. The American League record is held by theHouston Astros, who have appeared in the ALCS in seven straight seasons from 2017 to 2023 that has resulted in four pennants and two world titles. They are the only team to appear in an LCS in seven straight completed seasons, as the 90s Braves did not compete in the 1994 NLCS due to the season not being completed. Incidentally, the LCS was the only round preceding the World Series until 1995, when the Division Series was created; the Wild Card Series has acted as the first round for most of the playoff teams on a regular basis since 2022.
The Oakland Athletics in their "Swingin' A's" era previously held the AL record with five appearances in a row, which saw them win three world titles. The Yankees and Cardinals have each achieved an LCS appearance streak of four in a row. Three LCS appearances in a row have been achieved an additional thirteen times, and back-to-back LCS appearances an additional twenty-two times.
Three teams (the Orioles, Pirates, and Yankees) achieved multiple LCS appearance streaks in and around the 1970s, each adding up to five appearances in six years.
The LCS began in 1969. Before that, the two regular season champions were awarded the pennants and went directly to the World Series.

The Braves and the Yankees have achieved respective streaks of 14 and 13 consecutive appearances in the postseason, centered on the 1990s and 2000s. The Dodgers have an ongoing streak of 13 consecutive appearances, while the Astros and Braves saw respective streaks of eight and seven end in 2025. Five postseason appearances in a row have been achieved an additional eight times, four in a row an additional nine times, three in a row an additional thirty times, and back-to-back postseasons an additional fifty-three times.
Regarding near-streaks, the Yankees appeared in 17 of 18 postseasons from 1995 to 2012, 15 of 18 postseasons from 1947 to 1964 (see pennant near-streaks above), 8 of 10 postseasons from 2015 to 2024, and 7 of 8 postseasons twice, from 1936 to 1943 (see pennant near-streaks above). The Astros have appeared in 9 of 10 postseasons, from 2015 to 2024. In addition, three teams have appeared in postseason near-streaks of 7 (having appeared in 7 of 8 or 10 consecutive postseasons), while six teams have appeared in postseason near-streaks of 6 (having appeared in 6 of 7 or 8 consecutive postseasons). The Indians (1995 to 2001), St. Louis Cardinals (twice, 2000 to 2006 and 2009 to 2015), Red Sox (2003 to 2009), and Brewers (2018 to 2025) appeared in 7 of 8 postseasons, while the Phillies (1976 to 1983) and Angels (2002 to 2009) appeared in 6 of 8 postseasons.
Postseason appearance streaks have become more common in recent years, as the postseason has been progressively restructured to include more teams (originally two, four since 1969, eight since 1995, ten since 2012, sixteen in 2020, twelve since 2022). The Astros, who have reached the postseason eight straight times from 2017 to 2024, are the only team to ever win a postseason series in seven straight seasons.

The Houston Astros have achieved the longest series win streak of 7 consecutive postseasons, from 2017–2023. The Atlanta Braves are the next-closest team in consecutive seasons with at least one playoff series win, with 5 from 1995–1999. Four consecutive seasons with at least one postseason series win have been achieved twice, three seasons in a row an additional five times, and back-to-back postseason appearances with a series win an additional sixteen times.
Postseason series wins have become more common in recent years, as the postseason has been progressively restructured to include more teams (originally two, four since 1969, eight since 1995, ten since 2012, sixteen in 2020, twelve since 2022). Streaks predating 1995 are also included in the list of pennant streaks above.
