2015 NAIA baseball tournament

The 2015 NAIA baseball tournament was the 59th edition of the NAIA baseball championship. The 46-team tournament began on May 17 with Opening Round games across nine different sites and concluded with the 2015 NAIA World Series in Lewiston, Idaho that began on May 22 and ended on May 29. Lewis–Clark State (ID) defeated St. Thomas (FL) 10–7 in the championship game for their 17th 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 29 teams being awarded automatic bids as either champions and/or runners-up of their conferences, and 16 teams were selected at-large for the first time by the National Selection Committee, which was created as a pilot group for the 2015 season. 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
A total of 46 teams entered the tournament. As World Series host, Lewis–Clark State received an automatic bid into the NAIA World Series. 29 automatic bids were determined by either winning their conference's regular season championship, conference tournament, and/or conference tournament runner-up. The other 16 bids were at-large, with selections determined by the NAIA Baseball National Selection Committee.
