2023 Women's National Invitation Tournament

The 2023 Women's National Invitation Tournament was a single-elimination tournament of 64 NCAA Division I women's college basketball teams that were not selected for the field of the 2023 Women's NCAA Tournament. The tournament committee announced the 64-team field on March 13, following the selection of the NCAA Tournament field. The tournament started March 15 and ended on April 1 with the championship game televised by CBSSN. Kansas won the tournament for the first time in program history.

This was the final WNIT to be held with a 64-team format. On July 17, 2023, WNIT operator Triple Crown Sports announced that the tournament would be reduced to 48 teams starting in 2024. This followed the NCAA's announcement that it would launch the Women's Basketball Invitation Tournament, a 32-team direct parallel to the men's National Invitation Tournament, starting in the 2023–24 season.

Participants
The 2023 postseason WNIT field consists of 32 teams that received automatic berths - one berth from each conference - and 32 at-large teams. All Division I teams were considered for at-large berths, including those who are independent and/or are in the transition process of reaching full NCAA Division I status. Automatic berths went to the highest-finishing team in its conference's regular-season standings, not selected for an NCAA Tournament berth. The remaining team slots were filled by the top teams available.
