The Big 12 Conference women's basketball tournament is the championship women's basketball tournament in the Big 12 Conference. The tournament is set to be held at the T-Mobile Center in Kansas City, Missouri until 2031. Due to a major conference realignment that significantly impacted the Big 12, the 2025 women's tournament was the first tournament with 16 teams participating. At the beginning of the 2024–25 season, Arizona, Arizona State, Colorado, and Utah joined the conference. The tournament is sponsored by Phillips 66. The Tournament has been held every year since 1997, except in 2020 when it was cancelled due to the coronavirus pandemic.
