2021 Women's National Invitation Tournament

The 2021 Women's National Invitation Tournament was a tournament of 32 NCAA Division I teams that were not selected to participate in the 2021 NCAA Division I women's basketball tournament. The tournament committee announced the 32-team field on March 15, 2021, following the selection of the NCAA Tournament field. The tournament began on March 19, 2021, with the championship game on March 28, 2021. Rice won its first WNIT championship. All games were streamed on FloSports.

Format changes
Changes were made in order to ensure continued viability for the tournament during the COVID-19 pandemic. The field of teams was halved from 64 to 32. Games were not held on-campus; instead there were regional sites. Each conference was not guaranteed an automatic bid as they have been in the past. Teams also were not required to have at least a .500 record.

Participants
The 2021 WNIT field consisted of nine automatic invitations and twenty-three at-large teams. Automatic bids were given to regular season conference champions that did not win their conference tournaments, except for WAC regular season and conference tournament champion California Baptist, since they are still in transition to Division I and are ineligible to participate in the NCAA Women's Tournament until 2023.
