The 1990–91 season was the 94th season of competitive football in Scotland.

It was notable for the fact that there was a last day title decider at Ibrox between Rangers and Aberdeen.

Both teams went into the match level on points and goal difference, but Rangers needed to win the match because Aberdeen had scored two goals more.

Rangers won the title with a 2–0 win thanks to two goals by Mark Hateley.
