2019 NAIA baseball tournament

The 2019 NAIA baseball tournament was the 63rd edition of the NAIA baseball championship. The 46-team tournament began on May 13 with Opening Round games across nine different sites and concluded with the 2019 NAIA World Series in Lewiston, Idaho that began on May 24 and ended on May 31. Tennessee Wesleyan defeated St. Thomas (FL) 6–2 in a winner-take-all championship game for their second title in program history.

The 46 participating teams were selected from all eligible NAIA teams with the World Series host receiving an automatic bid to the NAIA World Series. The remaining 45 teams participated in the Opening Round with 32 teams being awarded automatic bids as either champions and/or runners-up of their conferences, and 13 teams were selected at-large by the National Selection Committee. Teams were then placed into one of nine pre-determined Opening Round sites of five teams a piece, each of which is conducted via a double-elimination tournament. The winners of each of the Opening Round sites plus the World Series host team participated in the NAIA World Series.

Tournament procedure

As World Series host, Lewis–Clark State received an automatic bid into the NAIA World Series. 32 automatic bids were determined by either winning their conference's regular season championship, conference tournament, and/or conference tournament runner-up.
