ASUN men's basketball tournament

The ASUN Conference men's basketball tournament (formerly known as the Trans America Athletic Conference men's basketball tournament between 1979 and 2001) is the conference championship tournament in basketball for the ASUN Conference, formerly known as the Trans America Athletic Conference (TAAC) and Atlantic Sun Conference. The tournament has been held every year since 1979, except for 1992–93.

It is a single-elimination tournament and seeding is based on regular season records. The winner, declared conference champion, receives the conference's automatic bid to the NCAA men's basketball tournament, as long as it is eligible for NCAA-sponsored postseason play. The eligibility issue applied in both 2021 and 2022, with each final featuring a team representing a transitional member of Division I (North Alabama in 2021 and Bellarmine in 2022 ). Under NCAA rules, a school transitioning from NCAA Division II is not eligible for NCAA-sponsored D-I postseason play (either the NCAA tournament or the NIT) during its four-year transitional period. North Alabama began its transition in July 2018 and was thus ineligible for the NCAA tournament or NIT through the 2021–22 season; Bellarmine began its transition in July 2020 and is thus ineligible for said events through 2023–24. Should a transitional school win the tournament, ASUN rules call for the regular-season champion to receive the automatic bid. North Alabama lost its final, making the issue moot for 2021, but Bellarmine won in 2022, giving Jacksonville State that season's automatic bid.

The Atlantic Sun tournament is the earliest of the NCAA Division I men's tournaments and its champion is the first to lock in an NCAA bid.
