The 2021 ACB Playoffs, also known as 2021 Liga Endesa Playoffs for sponsorship reasons, was the postseason tournament of the ACB's 2020–21 season, which began on 19 September 2020. The playoffs started on May 31 after the EuroLeague Final Four, which was played on May 28–30, and ended on June 15 before the Olympic Qualifying Tournaments, which will be played on June 29–July 4.
TD Systems Baskonia was the defending champion which got knocked out by Valencia Basket in the quarterfinals. Barça claimed their 16th ACB title and their 19th Spanish title, ending a 7-year drought, by downing archrivals Real Madrid in Game 2 of the Finals. Barça swept the series and completed its first Spanish double (League and Cup titles) since 2011.
On May 4, 2021, ACB delayed the regular season ending calendar one week to play the postponed matches.[1] With Barça's already qualified to the EuroLeague Final Four in Cologne, the playoffs will be played in best-of-three, instead of best-of-five as usual. Only if there had been no Spanish representation in the Final Four, the finals would have been played to best-of-five.[2] [3]
At the end of the regular season, the eight teams with the most wins qualified for the playoffs. The seedings were based on each team's record. The bracket was fixed; there was no reseeding. All rounds were best-of-three series; the series ended when one team won two games, and that team advanced to the next round. All rounds, including the Finals, were in a 1–1–1 format. Home court advantage went to the team with the better regular season record, and, if needed, ties were broken based on head-to-head record.
On March 16, 2021, Real Madrid became the first team to clinch a playoff spot.[4]
