The 1990 Saskatchewan Roughriders season was the 76th season in the club's 80th year of existence. Following their win in the 1989 Grey Cup, the team opened this season as defending Grey Cup champions for the first time since 1967. The team finished in third place in the Canadian Football League's West Division with a 9–9 record for the second consecutive season.

- most pass completions in a season (450), which has been surpassed by several teams.

They set the following team records:
