Media writers generally state that the rivalry between the two teams solidified in the 2010s, after both teams formed "Big Threes" that began to face each other in multiple consecutive playoff matchups.
The two teams have met each other in fourEastern Conference Finals: 2012, 2020, 2022, and 2023. All seven years the two teams have met in the postseason, the winner made the NBA Finals that year.
While theBoston Celticsformed in 1946, theMiami Heat began play in1988 as an expansion franchise. The Celtics and Heat first played against each other on November 15, 1988; playing on the road, the Celtics defeated the Heat 84–65. Boston would win their first ten matchups against Miami.[1]
AnApril 1991 game between the two sides featured the Celtics'Reggie Lewis scoring a career high 42 points in a 119–109 victory for Boston.[2] InDecember 1995, the Celtics narrowly won a double overtime game against the Heat 121–120.[3]
In 1995, head coachPat Riley resigned from the Knicks via fax to become president and head coach of the Miami Heat, with complete control over basketball operations. Riley's addition marked the moment the Miami Heat became an NBA Finals contender. Prior to a five-year run as Knicks coach, Riley was the head coach for theShowtime Lakers from 1981 to 1990 and a big part of theCeltics-Lakers rivalry. Riley, along with star playersDwyane Wade andShaquille O'Neal, would later lead the Heat to their first championship in franchise history in2006.
The two teams met in the playoffs for the first time in2010, in thefirst round. The #4-seed Celtics were led by theirBig Three ofPaul Pierce,Ray Allen, andKevin Garnett. The #5-seed Heat were led byDwyane Wade, who averaged 33.2 points, 5.6 rebounds, and 6.8 assists in the series.[4][5] During the first game of the series, Garnett elbowed Heat forwardQuentin Richardson, after Richardson walked up to Paul Pierce while injured insinuating Pierce was faking his injury.[6][7] This led to an on-court dust-up between the two sides and as a result, Garnett received a suspension for game two of the series and Richardson was fined.[7] In Game 4, Wade dropped 46 points to avoid getting swept. However, the Celtics won in five games.[5][8]
During the subsequent offseason, the Heat signedLeBron James andChris Bosh.[9] Along with Wade, the three formedMiami's own "Big Three".[10] James announced his decision to sign with the Heat inThe Decision, a television special that garnered him much criticism.[11] In particular, James had developed a personal rivalry with the Celtics during his time withCleveland Cavaliers as the Celtics eliminated the Cavaliers in the playoffs in 2008 and 2010.[12] NBA.com writer John Schuhmann wrote: "If the Celtics' big three didn't come together in 2007 via a pair of big trades, the Heat's big three probably wouldn't have come together last summer via free agency. Boston is the blueprint. Miami is the newer, more talented version."[13] The NBA scheduled the Celtics and Heat to play against each other for the2010–11 NBA season's opening day.[14]
Near the end of 2010,The New York Times wrote on a Celtics win over theNew York Knicks: "With their win over the Knicks on Wednesday, the Celtics conquered the NBA, though Boston fans now demonize the Miami Heat as surrogateYankees," referencing theYankees–Red Sox rivalry.[15]
Dwyane Wade andLeBron James helped propel the Heat over the Celtics in the 2011 and 2012 postseasons
Now with James and Bosh on the roster, the two teams met in the2011 Eastern Conference Semifinals. As the #2-seed, the Heat had home court advantage over the #3-seed Celtics. James called the series "personal" for him, citing his losses to the Celtics while a member of the Cavaliers.[16] In Game 5 of the series, Wade and James scored 34 and 33, respectively.[17] James went on a 10–0 scoring run to close out game, securing a 4–1 series win for the Heat. The Celtics and Heat once again faced off in the postseason in 2012, this time in theEastern Conference finals (ECF).[18] The Heat were the #2-seed while the Celtics were the #4-seed, giving the Heat home court advantage. James fouled out of Game 4, while Wade missed a potential game-winning basket at the buzzer.[19] Later, down 3–2 in the series, the Heat went on the road to face the Celtics in game six of the series. Helping the Heat tie the series, James had 45 points, 15 rebounds, and five assists.[20] Praised by basketball media at the time,[12][21] sportswriters have also retrospectively noted James' game six performance as one of his best and most important.[22][23][24] The Heat won the series 4–3 after winning Game 7 by a score of 101–88.[12][25] James later stated that he feared a loss to the Celtics in 2012 would have caused the Heat's Big Three to break up before winning a championship.[26]
With these three straight postseason meetings, the Heat's rivalry with the Celtics became their most notable since theirrivalry with the Knicks, according toBleacher Report.[27] Boston'sRajon Rondo also played a pivotal role in the rivalry during this period. Writing forBusiness Insider, Tony Manfred stated much of the rivalry was based on off-court narratives, but called Rondo "the only reason these two team have an actual on-court rivalry."[28] Writing forBleacher Report, Jason Reindollar called the rivalry between the two teams "official" following their 2012 ECF matchup.[14]
Ray Allen departed Boston and signed with the Heat in 2012
During the offseason, Allen signed with the Heat.[29] A rift between Allen and Rondo was cited as a factor for Allen's departure from Boston.[28] Garnett, Rondo, and Pierce were reported to hold a grudge with Allen for multiple years after.[30][31]Doc Rivers, who coached the Celtics from 2004 to 2013, has discussed the rift and taken blame for it.[32] The two teams opened up their2012–13 NBA season playing against each other in Miami.[33] The game continued the rivalry's intense and physical nature, with Rondo being noted to grab Wade around the neck in the game.[29] During the season, the Heat achieved a 27-game win streak, which included a game against the Celtics. The game featured James finishing afast break by dunking onJason Terry, a "personal rival" of James' according toBrian Windhorst.[34]
The two front offices would get involved in the rivalry in the middle of the 2012–13 season. During a radio interview, Celtics general managerDanny Ainge criticized James for his complaints about officiating, causing Heat general managerPat Riley to issue a statement, saying: "Danny Ainge needs to shut the fuck up and manage his own team. He was the biggest whiner going when he was playing, and I know that because I coached against him."[35] In response, Ainge would issue a statement of his own: "I stand by what I said. That's all. I don't care about Pat Riley. He can say whatever he wants. I don't want to mess up his Armani suits and all that hair goop. It would be way too expensive for me."[36] The two were noted to have a personal rivalry stemming for 30 years, dating back to when Ainge played for the Celtics and Riley was the head coach of theLos Angeles Lakers, which itself was avery storied team rivalry.[35] Ainge would eventually tellThe Boston Globe "we're both right. LeBron should stop complaining and I should manage my own team." Both head coaches expressed amusement with the exchange between their general managers, with Rivers calling it "cool" and jokingly suggesting that Riley and Ainge "should duke it out", and Heat coachErik Spoelstra stating "I love direct GM to GM communication. That's awesome."[37]
The Heat did not meet the Celtics in the2013 postseason, but Allen helped the Heat win their second consecutive championship with a clutch game-tying shot in game six of theFinals.[38]
Boston'sJayson Tatum and Miami'sJimmy Butler were the first two winners of theLarry Bird Trophy for their performances in the 2022 and 2023 Eastern Conference Finals, respectively.
Two years later, the Celtics and Heat faced off against each other in another ECF matchup, with the Heat as the #1-seed and the Celtics as the #2-seed.[43] Sportswriters noted the series as having drastic swings, calling it an "ugly" and "physical, back-and-forth" affair.[45][46][47] Writing forSports Illustrated, Chris Mannix commented that game five was a particularly bad viewing experience, citing the two teams' poor offensive performances.[46] Down 3–2 in the series, Butler scored 47 points, while also grabbing nine rebounds and recording eight assists to help Miami force a Game 7.[48][49] Butler's performance drew comparisons to James' 45-point performance from a decade prior.[48][50] Down by two with under a minute left in the game, Butler attempted a three-pointer to put the Heat ahead but missed.[51] The Celtics defeated the Heat 100–96 on the road in Game 7, winning the series and clinching a berth to the2022 NBA Finals.[51] It also was Boston's first postseason win against Miami since 2010.Jayson Tatum scored 26 points in the game for the Celtics and was awarded the inaugural Eastern Conference Finals MVP award, dubbed theLarry Bird Trophy.[51]

The Celtics would respond by winning the next three games, punctuated with a go-ahead shot with 0.2 seconds left on the clock byDerrick White during Game 6 in Miami. In doing so, the Celtics became the fourth team in NBA history to force a Game 7 after going down 0–3, and the only one to force a Game 7 at home.[55] Tatum injured his ankle on the first possession of Game 7, though remained in the game.[56] Miami won the deciding game in Boston, resulting in the Heat becoming the second #8-seed in NBA history to reach the Finals and avoiding the distinction of becoming the first team to squander a 3–0 playoff series lead. Butler won the Larry Bird Trophy as the Eastern Conference finals MVP, succeeding Tatum.
In the2023–24 NBA season, the Celtics were dominant, winning a league-leading 64 games in the regular season and clinching the #1-seed in the East.[57] Conversely, the Heat narrowly made the playoffs, clinching the #8-seed through theplay-in tournament.[58] The two teams met in the first round of the playoffs, though the Heat were without Butler for the series due to a knee injury he sustained in the play-in.[59] The series was tied after two games, with the Heat setting a franchise playoff record for three-pointers made in Game 2, though the Celtics were able to dispatch the Heat in five games en route to a2024 NBA Finals victory.[60][61]
