The 2019 Conference USA men's basketball tournament was the concluding event of the 2018–19 Conference USA (C-USA) men's basketball season. It was held from March 13–16, 2019 alongside the C-USA women's tournament in Frisco, Texas, at the Ford Center at The Star. In the first round and quarterfinals, two games were played simultaneously within the same arena, with the courts separated by a curtain. Old Dominion defeated Western Kentucky 62–56 in the championship game to win the tournament, and received the conference's automatic bid to the 2019 NCAA tournament. It was their first Conference USA title since joining the conference six years ago.
