Ohio Valley Conference baseball tournament

The Ohio Valley Conference baseball tournament is the conference baseball championship of the NCAA Division I Ohio Valley Conference. In the current format, established in 2023, the top eight regular-season finishers of the conference's 10 baseball schools qualify for the tournament. The bottom four seeds play single-elimination games, paired by seeds as 5–8 and 6–7. The winners of those games advance to single-elimination games, with the 3 and 4 seeds respectively playing the lower and higher seeds among the first-round winners. At this point, the top two seeds join, and the tournament becomes double-elimination. The most recent 2023 edition was held at the venue now known as Marion Stadium in Marion, Illinois. The winner of the tournament receives an automatic berth to the NCAA Division I Baseball Championship.
