The 2023 NCAA Division I baseball season, play of college baseball in the United States organized by the National Collegiate Athletic Association (NCAA) at the Division I level, began on February 17, 2023.
The regular season was followed by many conference tournaments and championship series, and the season concluded with the 2023 NCAA Division I baseball tournament and 2023 Men's College World Series.
The Men's College World Series, consisting of the eight remaining teams in the NCAA tournament and held annually in Omaha, Nebraska, at Charles Schwab Field Omaha, ended on June 26, 2023, with LSU winning the title.
Incarnate Word had announced plans to leave the SLC for the WAC after the 2022 season,[17] but days before that move was to take effect, the school announced it was staying in the SLC.
The teams in each conference that win their regular season title are given the number one seed in each tournament.
