2020 NCAA Division I baseball season

The 2020 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 14, 2020. On March 12, it was announced that the 2020 NCAA tournament would be canceled due to the coronavirus pandemic. The decision whether to continue with an abbreviated season was left to individual schools and conferences.

Realignment

 * Savannah State moved all sports to NCAA Division II, departing the Mid-Eastern Athletic Conference and returning to its former home of the Southern Intercollegiate Athletic Conference.
 * Boise State restarted its program within the Mountain West Conference, but dropped it again in July due to a reduction in the athletic department's budget. Boise State previously dropped baseball after the 1980 season.
 * Merrimack upgraded all sports, including baseball, to NCAA Division I from NCAA Division II, joining the Northeast Conference.

Format changes

Ballpark changes

 * The 2020 season was to be the first for UConn at Elliot Ballpark, replacing J. O. Christian Field. The team was originally scheduled to play its first game there on March 29 against Seton Hall.
 * Oklahoma State originally planned to inaugurate O'Brate Stadium on March 20, 2020, replacing Allie P. Reynolds Stadium after the first 14 home games of the 2020 season. The first scheduled game at the new ballpark was against the TCU Horned Frogs. Oklahoma State's season was canceled on March 13.
 * The 2020 season was the last for Florida at McKethan Stadium, before the season was canceled on March 17. The team's last game at the venue was on March 10, a loss against the rival Florida State Seminoles.
