2012 NAIA baseball tournament

The 2012 NAIA baseball tournament was the 56th edition of the NAIA baseball championship. The 46-team tournament began on May 10 with Opening Round games across nine different sites and concluded with the 2012 NAIA World Series in Lewiston, Idaho that began on May 25 and ended on June 1. Tennessee Wesleyan defeated Rogers State (OK) 10–6 in the championship game for their 1st 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, which were determined by the final NAIA Baseball Coaches' Top 25 Poll. 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
