The 2025 Atlantic Sun men's basketball tournament was the conference postseason tournament for the Atlantic Sun Conference. The tournament was the 46th year the league has conducted a postseason tournament. The tournament was held March 2âÂÂ9 at campus sites of the higher seeds. The winner, Lipscomb, received the conference's automatic bid to the 2025 NCAA Tournament.
Ten teams are contesting the bracket. All rounds reseed instead of a traditional set bracket; to that end, the 9 and 10 seeds play each other in round 1, and the 7 and 8 seeds do as well, rather than the more common 7/10 and 8/9 matchups.
The three tiebreakers used by the ASUN are: 1) head-to-head record of teams with identical record, 2) comparison of tied teams' win-loss percentage vs. the top ranked team (or teams as a group in the event that they are tied), descending to the next highest placed team(s) until an advantage is gained and 3) NCAA NET rankings available on day following the conclusion of ASUN regular season play. If an advantage is gained in a tiebreaker of three or more teams, that team or teams is pulled out, and the remaining tied teams start back at step 1. If more than one team is pulled out, that set of teams would also start back at step 1.
