Longest Game in NBA History

On January 6, 1951, the Indianapolis Olympians and Rochester Royals played the longest game in NBA history. The game required six overtime periods before Indianapolis finally won 75-73.

A normal NBA game lasts 48 minutes. Six five-minute overtime periods increased the playing time to 78 minutes.

The unusually low score is a product of the era. The game was played before the NBA introduced the 24-second shot clock, allowing teams to hold the ball for extended periods without attempting a shot.

The six-overtime record has stood since 1951 and remains one of the oldest team records in NBA history.

Five-Overtime Games

Only two other NBA games have reached five overtimes.

On November 24, 1949, the Syracuse Nationals defeated the Anderson Packers 125-123 after five overtime periods.

Forty years later, the Milwaukee Bucks defeated the Seattle SuperSonics 155-154 in five overtimes on November 9, 1989. Seattle's Dale Ellis played an NBA-record 69 minutes in that game.

Longest NBA Playoff Games

Two NBA playoff games have reached four overtime periods.

On March 21, 1953, the Boston Celtics defeated the Syracuse Nationals 111-105 in four overtimes during the Eastern Division Semifinals.

On May 3, 2019, the Portland Trail Blazers defeated the Denver Nuggets 140-137 in four overtimes during the Western Conference Semifinals. The game lasted 68 minutes, with Nikola Jokic playing 65 minutes and CJ McCollum leading Portland with 41 points.
