The 2021 Saskatchewan Roughriders season was the 63rd season for the team in the Canadian Football League. It was the club's 112th year overall, and its 105th season of play. Although the club failed to record a second consecutive first place finish in the West Division, the Roughriders qualified for the post-season for the fourth consecutive season of play on October 30, 2021 following a win over the Montreal Alouettes. After defeating the Calgary Stampeders in the West Semi-Final, the Roughriders then lost the West Final to the Winnipeg Blue Bombers for the second consecutive season. This was the second season under head coach Craig Dickenson and general manager Jeremy O'Day.
