2018 American Athletic Conference baseball tournament

The 2018 American Athletic Conference baseball tournament was scheduled to be held at Spectrum Field in Clearwater, Florida, from May 22 through 26. Anticipated weather forced a truncated schedule causing the event to be condensed, and the title game was played on May 25. The event, held at the end of the conference regular season, determines the champion of the American Athletic Conference for the 2018 season. East Carolina won the double-elimination tournament and received the conference's automatic bid to the 2018 NCAA Division I baseball tournament.
