The 1989 Iowa State Cyclones football team represented Iowa State University during the 1989 NCAA Division I-A football season. They played their home games at Cyclone Stadium in Ames, Iowa. They participated as members of the Big Eight Conference. The team was led by third-year head coach Jim Walden.

This was also the first time Iowa State played against Minnesota since 1923. On October 8, 1923, Jack Trice, an Iowa State athlete and one of the first college football players to be African-American, died after suffering injuries in a game against Minnesota that occurred two days before his death. There was speculation that the injuries caused by the Minnesota players were intentional. Because of this, Iowa State did not renew their contract to play with Minnesota until the 1989 season.^[1]
