The Big 12 men's basketball tournament (known since its inception in 1997 under sponsorship agreements as the Phillips 66 Big 12 men's basketball tournament) is the championship men's basketball tournament in the Big 12 Conference. It is a single-elimination tournament of four rounds, with the top six seeds getting byes in the first round.^[2] Seeding is based on regular season records. The winner of the tournament receives the Big 12 Conference automatic bid to the NCAA Championship tournament.

Between 2005 and 2019, no current Big 12 member besides Iowa State or Kansas won the tournament, and those two schools have won 18 of 27 titles. The remaining current Big 12 schools only account for six additional tournament titles. For its first twenty-three years, no school from outside the original Big Eight Conference had ever won the tournament. This streak ended when the Texas Longhorns won the championship game against Oklahoma State in 2021.

The tournament is set to be held at the T-Mobile Center (formerly Sprint Center) in Kansas City, Missouri until 2031.^[3]
