1998 Conference USA men's basketball tournament

The 1998 Conference USA men's basketball tournament was held March 4–7 at the Myrl H. Shoemaker Center in Cincinnati, Ohio.

The Bearcats, in turn, received an automatic bid to the 1998 NCAA tournament.

They were joined in the tournament by fellow C-USA members UNC Charlotte and Saint Louis, who earned at-large bids.

Prior to the season, Conference USA dropped their old regular season scheduling format of three divisions of four teams (Red, White, and Blue) in favor of two six-team divisions (American and National).

All seeds were determined by overall regular season conference records.
