The 1989 Saskatchewan Roughriders was the club's 80th year of operation, 75th season of play, and its 32nd season in the Canadian Football League. The team finished in third place in the CFL West Division with a 9–9 record. The Roughriders defeated the Calgary Stampeders in the West Semi-Final and then defeated the heavily-favoured Edmonton Eskimos who had finished with a CFL-record 16 regular season wins. Due to their West Final win, the Roughriders qualified for their first Grey Cup game since the club's loss in the 1976 championship game.
In the 77th Grey Cup, the team faced the 12–6 Hamilton Tiger-Cats who had already defeated the Roughriders in both regular season matches. However, the Roughriders kept it a close game and ultimately won with a Dave Ridgway field goal to win the championship. It was Saskatchewan's first Grey Cup win in 23 years (since the 1966 Grey Cup), and only their second in team history.
