2018 Big 12 Conference baseball tournament

The 2018 Big 12 Conference baseball tournament was held from May 23 through 27 at Chickasaw Bricktown Ballpark in Oklahoma City, Oklahoma. The annual tournament determines the conference champion of the Division I Big 12 Conference for college baseball. The winner of the tournament will earn the league's automatic bid to the 2018 NCAA Division I baseball tournament.
The tournament has been held since 1997, the inaugural year of the Big 12 Conference. Among current league members, Texas won the most championships with five. Among original members, Baylor and Kansas State have never won the event. Iowa State discontinued their program after the 2001 season without having won a title. Having joined in 2013, TCU won their first title in 2014 while West Virginia has yet to win the Tournament.
