There is no stage in basketball brighter than the NBA Finals, which is what makes a comeback there feel almost impossible. The defense tightens, every possession is scrutinized, and a big lead is supposed to be safe. So when a team claws back from 20 or more points down on this stage, it becomes instant history. Which raises the obvious question: what is the largest comeback in NBA Finals history, and how does the rest of the list stack up behind it?
For years the record belonged to the 2008 Celtics, but it was just shattered in dramatic fashion, and the single-game list is full of franchise-defining moments from Houston in 1995 to Dallas in 2011. There is also a separate kind of comeback worth knowing: the greatest series rally of all time.
The chart below ranks the biggest single-game Finals comebacks from largest to smallest, with the deficit, the result, and the year for each. Take a look, then we’ll break down the moments that matter most.

The Largest Comeback in NBA Finals History
The record now belongs to the New York Knicks. In Game 4 of the 2026 Finals at Madison Square Garden, the Knicks trailed the San Antonio Spurs by 29 points before storming all the way back to win 107 to 106 on an OG Anunoby tip-in with 1.2 seconds left.
The Spurs had led by 27 at halftime, the third-largest halftime lead in Finals history, and then scored just 30 points in the entire second half. The win gave New York a 3 to 1 series lead and stands as the biggest single-game comeback the Finals has ever seen.
The Record It Broke
Before that night, the mark belonged to the 2008 Boston Celtics. In Game 4 against the Los Angeles Lakers, Kobe Bryant’s team raced out to a 45 to 21 lead, only for Boston to erase the 24-point deficit and win 97 to 91.
That comeback flipped what could have been a tied series into a commanding 3 to 1 Celtics lead, and they closed it out for the franchise’s 17th title. For 18 years it stood as the gold standard of Finals comebacks.
The Other 20-Point Comeback
Only three teams have ever overcome a deficit of 20 or more points in the Finals, and the third is one of the most famous games of the 1990s. In Game 1 of the 1995 Finals, the heavily favored young Orlando Magic of Shaquille O’Neal and Penny Hardaway built a 20-point lead over the defending champion Houston Rockets.
Then Kenny Smith caught fire, hitting a Finals-record seven three-pointers, Nick Anderson missed four late free throws, and Hakeem Olajuwon tipped in the winner in overtime. Houston won 120 to 118 and went on to sweep the series.
The Greatest Series Comeback
Single-game rallies are only one kind of comeback. The greatest series comeback in Finals history came in 2016, when LeBron James and the Cleveland Cavaliers became the only team ever to erase a 3 to 1 series deficit to win the title, beating the 73-win Golden State Warriors in seven games.
No team had ever done it before, and none has since. It is a different category from the single-game list, but it belongs in any conversation about the biggest comebacks the Finals has produced.
Why Finals Comebacks Are So Rare
Big comebacks are harder in the Finals than at any other point in the season. These are the two best teams in the league, defenses are sharper, rotations are tighter, and coaches have days between games to prepare.
A 20-point lead in June is far more secure than the same lead in a regular-season game, which is exactly why the handful of teams that have overcome one are remembered for it. For perspective, the largest comeback in any NBA playoff game is 31 points, by the Clippers in the 2019 first round, and the all-time regular-season record is 36 points, but the Finals stage makes even a 24-point rally feel monumental.
The Bottom Line
The largest comeback in NBA Finals history is the Knicks’ 29-point rally over the Spurs in 2026, which broke the 24-point mark set by the 2008 Celtics.
Only three teams have ever come back from 20 or more down on this stage, and on the series side, the 2016 Cavaliers remain the only team to escape a 3 to 1 hole. Whether measured by a single quarter or a full seven games, these are the moments that prove no lead is truly safe when a title is on the line.
