† 2003 Atlantic Sun Tournament winner As of March 4, 2003 Rankings from AP Poll

Troy State defeated UCF in the championship game, 80–69, to win their first Atlantic Sun men's basketball tournament.

The Trojans, therefore, received the Atlantic Sun's automatic bid to the 2003 NCAA tournament, their first appearance in the Division I tournament.

Format

The Atlantic Sun's membership remained fixed at twelve, so no changes to the format were required. As such, only the top eight teams from the conference tournament were eligible for the tournament. These eight teams were seeded based on regular season conference records.
