The 2021 WNBA season was the 25th season of the Women's National Basketball Association (WNBA). The Seattle Storm were the defending champions. In the playoffs, the Chicago Sky won in four games over the Phoenix Mercury. Due to the COVID-19 pandemic, teams played a 32-game season (rather than the 36 games agreed to in the original 2020 season schedule) that included mini two-game series to reduce travel. The regular season ran from May 14 to September 19, with a break from July 12 to August 11 for the Olympic Games.

This season also marked the launch of the WNBA Commissioner's Cup, which had been intended to start in the 2020 season but was delayed due to COVID-19. The first home game and first away game for each team against each of its conference opponents doubled as Cup games; all such games were played before the league took its Olympic break. The Cup final, officially called the Commissioner's Cup Championship Game, featured the conference leaders in the Cup standings and was held on August 12, three days before the rest of the league resumed play, at the Footprint Center in Phoenix, Arizona. A prize pool of $500,000 was provided for the Cup, with players on the winning team guaranteed a minimum bonus of $30,000 and those of the losing team guaranteed $10,000, and the championship game MVP receiving an extra $5,000. The Seattle Storm defeated the Connecticut Sun 79-57 to win the inaugural cup. Breanna Stewart was named MVP of the game.

The season had 100 games broadcast on national networks, including 25 across ABC and ESPN networks, 40 on CBS networks, and 35 on NBA TV. The remainder of games were broadcast on local networks and the WNBA's League Pass service; several games were also streamed on Twitter, Amazon Prime, and Oculus.

This season saw Wilson take over as the league's ball supplier. Spalding previously held the contract for the league's first 24 seasons.

Draft

The New York Liberty won the first pick in the 2021 WNBA draft in the draft lottery, but the pick was later traded to the Dallas Wings who picked Charli Collier.
