The longest winning streaks in National Basketball Association (NBA) history are presented on two lists. One list counts only regular-season games, including streaks that started in one season and carried over into the following season. The other list is made up of playoff games only.
The Los Angeles Lakers own the longest winning streak in NBA history. They won 33 straight games in the 1971–72 season, compiling a season-best 69–13 record and went on to win the NBA Finals. In the 2016–17 season, the Golden State Warriors posted a season-best 67–15 regular-season record and began the 2017 playoffs with a 15-game win-streak, the most consecutive wins in NBA playoff history. They went on to win the NBA Championship with a 16–1 (.941 winning percentage) record, the best playoff record in NBA history.[1]
The Los Angeles Lakers appear six times across both lists, with four streaks over 15 games in the regular season and two over ten games in the postseason. The Boston Celtics appear six times, with five streaks in the regular season, and one in the postseason. The Milwaukee Bucks appear five times, with all five streaks in the regular season. The San Antonio Spurs appear four times, with 2 streaks in the regular-season and 2 in the postseason.
