The 2018 Missouri Valley Conference baseball tournament was held from May 23 through 26. All eight baseball-sponsoring schools in the conference participated in the double-elimination tournament that was held at Dallas Baptist's Horner Ballpark in Dallas, Texas. The winner of the tournament earned the conference's automatic bid to the 2018 NCAA Division I baseball tournament.[1]
The league's eight teams were seeded based on conference winning percentage. The teams played a two bracket, double-elimination format tournament, with the winner of each bracket then playing a single elimination final.
