The 2022 NAIA baseball tournament was the 65th edition of the NAIA baseball championship. The 46-team tournament began on May 16 with Opening Round games across ten different sites and concluded with the 2022 NAIA World Series in Lewiston, Idaho that began on May 27 and ended on June 3. Southeastern (FL) defeated host Lewis–Clark State 11–5 in a winner-take-all championship for their second title in program history. Lewis–Clark State forced a winner-take-all championship game with a 10–9 victory over Southeastern earlier in the day.
For the first time since the Opening Round format began in 2009, the World Series host would be playing in the Opening Round instead of getting a direct entry into the NAIA World Series. To accommodate the automatic bid for the World Series host in the Opening Round, the tournament field expanded from 45 to 46 teams along with a tenth Opening Round site being added.
The 46 participating teams were selected from all eligible NAIA teams. The World Series host and 30 teams were awarded automatic bids as either champions and/or runners-up of their conferences, and 15 teams were selected at-large by the National Selection Committee. Teams were then placed into one of ten pre-determined Opening Round sites, with six sites consisting of five teams and four sites consisting of four teams, each of which is conducted via a double-elimination tournament. The winners of each of the Opening Round sites participated in the NAIA World Series.
Tournament procedure
A total of 46 teams entered the tournament, with Lewis–Clark State receiving an automatic bid into the Opening Round as World Series host. 30 automatic bids were determined by either winning their conference's regular season championship, conference tournament, and/or conference tournament runner-up. The other 15 bids were at-large, with selections determined by the NAIA Baseball National Selection Committee.
