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.

During this time, the NAIA tournaments featured 32 teams with the entire events contested at a single arena over the course of one week.

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.

For the first eleven years that the NAIA sponsored women's basketball, it held a single national championship for all programs across its entire membership.

The NAIA Women's Basketball National Championship Tournament was most recently held at the Rimrock Auto Arena at MetraPark in Billings, Montana, which hosted from 2017 until the return to a single division after the 2019–20 season.
