1989 Colonial Athletic Association baseball tournament
The 1989 Colonial Athletic Association baseball tournament was held at Brooks Field on the campus of UNC Wilmington in Wilmington, North Carolina, from May 12 through 15. The event determined the champion of the Colonial Athletic Association for the 1989 season. The winner of the tournament, second-seeded, earned the CAA's automatic bid to the 1989 NCAA Division I baseball tournament.
For the first three years of the event, a different team won the Tournament. Richmond, East Carolina, and George Mason each won once. With their victory in 1989, East Carolina became the first program to win multiple championships. During their tenure in the CAA which ended after the 2001 season, the Pirates would claim seven titles overall.
