The 1981 Trans America Athletic Conference men's basketball tournament (now known as the ASUN men's basketball tournament) was held March 4–8 at the Hirsch Memorial Coliseum in Shreveport, Louisiana.[1]
Mercer upset top-seeded in the championship game, 72–67, to win their first TAAC/Atlantic Sun men's basketball tournament. The Bears, in turn, received the TAAC's automatic bid to the 1981 NCAA tournament. This was Mercer's first appearance in the Division I NCAA tournament.
