Georgia State defeated Arkansas–Little Rock in the championship game, 80–60, to win their first TAAC/Atlantic Sun men's basketball tournament.
The Panthers, therefore, received the TAAC's automatic bid to the 1991 NCAA tournament, their first Division I tournament appearance.
Hardin–Simmons departed the TAAC for Division III prior to the season, leaving the conference membership at eight. As such, the TAAC tournament returned to its old format where all of the league's members participated.
