The 1989 Jacksonville State Gamecocks football team represented Jacksonville State University as a member of the Gulf South Conference (GSC) during the 1989 NCAA Division II football season.
Led by fifth-year head coach Bill Burgess, the Gamecocks compiled an overall record of 13–1 with a mark of 8–0 in conference play, winning the GSC title.
For the second consecutive season, Jacksonville State advanced to the NCAA Division II Football Championship playoffs, beating Alabama A&M in the first round, North Dakota State in the quarterfinals, and Angelo State in the semifinals, before losing to Mississippi College in the championship game.
In 1993, the NCAA vacated Mississippi College's championship as a result of numerous violations, but the Gamecocks are still recognized as runner-up.
