The American Athletic Conference men's basketball tournament (sometimes known simply as The American Championship) is the conference tournament in basketball for the American Athletic Conference. It is a single-elimination tournament that involves all league schools (14 as of the 2023–24 season^[1]). Its seeding is based on regular season records. The winner receives the conference's automatic bid to the NCAA men's basketball tournament; however, the official conference championship is awarded to the team or teams with the best regular season record.

The creation of the conference tournament was a product of the split of the original Big East Conference. While The American is the legal successor to the old Big East, it gave up the rights to the long-standing conference tournament at Madison Square Garden in New York City to the new Big East. As a result, the 2014 tournament was numbered as the first tournament for the conference.

† Louisville was forced to vacate their 2014 win due to 2015 sex scandal
