The NCAA Division III Baseball Tournament is an annual college baseball tournament held at the culmination of the spring regular season to determine the NCAA Division III baseball champion. The tournament has been played since 1976, soon after the formation of Division III. Most of the 56 teams who qualify do so by winning an automatic bid that comes along with their conference's championship; others receive at-large bids. The initial round consists of six- and eight-team regionals held at pre-selected sites in eight regions: New England, New York, Mid-Atlantic, South, Mideast, Midwest, Central, and West. The eight regional champions advance to the final round of the Division III Baseball Championship tournament,
which will be hosted at Veterans Memorial Stadium in Cedar Rapids, Iowa in 2019. The event was formerly held at Fox Cities Stadium in Grand Chute, Wisconsin, just outside of Appleton until 2018.
In both the regional and final rounds, the tournament uses a "double elimination" format, in which teams must lose twice to be eliminated.
