1971 NBA playoffs

The 1971 NBA playoffs was the postseason tournament of the National Basketball Association's 1970–71 season. The tournament concluded with the Western Conference champion Milwaukee Bucks defeating the Eastern Conference champion Baltimore Bullets four games to none in the NBA Finals.

Led by Finals MVP and the previous season's Rookie of the Year Lew Alcindor and Oscar Robertson, the Bucks became the fastest expansion team in NBA history to win the championship (a record that they still hold as of 2021), and did so in dominating fashion, finishing 12-2 in the playoffs with a postseason average point differential of 14.5.

The playoff format kept the amount of teams qualifying the same, albeit with a different format from the two-division format, since there were now four divisions rather than two, with each division qualifying its champion and second-place team (as opposed to having the top four from the Eastern and Western). In the Conference Semifinals, the champion of each division played the second place team in the other, with the divisional champion having home-court advantage. The two winners then played for the conference championship.

This was the first NBA Finals appearance for the Bullets, and their only trip to the championship round in Baltimore; they made three more appearances (winning one title) later in the decade.

The 1971 playoffs was the last for the San Francisco Warriors under that moniker; the following season, symbolizing their already-established home base of Oakland, they changed their name to the Golden State Warriors.
