The NAIA women's basketball tournament has been held annually by the National Association of Intercollegiate Athletics since 1981 to determine the national champion of women's college basketball among its members in the United States and Canada.
The tournament was created to crown a women's national title for smaller colleges and universities, debuting one year before the first NCAA women's basketball tournament in 1982.
From 1992 to 2020, the NAIA sponsored two championships, one for its Division I members and another for those in its Division II. Both tournaments moved venues several times during the existences, with the final locations ultimately being Billings, Montana for Division I and Sioux City, Iowa for Division II. During this time, the NAIA tournaments featured 32 teams with the entire events contested at a single arena over the course of one week. Following renewals, the 2018 and 2019 tournaments were held in those same cities, but the 2020 tournaments were called off due to the COVID-19 outbreak.
From 2021, the two tournaments were merged back into a single event, which initially featured 48 teams in 2021 before expanding to 64 teams in 2022. Since the expansion of the tournament to its current size, the format of the event has featured teams beginning play at one of sixteen regional sites with the winners of those regionals advancing to play in a final, four-round national tournament in Sioux City, Iowa.
Dordt are the defending champions, winnining their first national title in 2024.
