The 1990–91 QMJHL season was the 22nd season in the history of the Quebec Major Junior Hockey League. The league inaugurates the St-Clair Group Plaque, awarded to the "Marketing Director of the Year." Dilio and Lebel divisions are restored as the league adds an expansion franchise in Beauport, Quebec, a suburb of the provincial capital. Twelve teams played 70 games each in the schedule.
The Chicoutimi Saguenéens finished first overall in the regular season, winning their first Jean Rougeau Trophy, backstopped by Goaltender of the Year and Playoff MVP, Felix Potvin. Chicoutimi won its first President's Cup, defeating the Drummondville Voltigeurs in four games.
