The 1985–86 QMJHL season was the 17th season in the history of the Quebec Major Junior Hockey League. The league loses one of its charter members in the offseason, when the Quebec Remparts suspend operations. The remaining ten teams played 72 games each in the schedule. Gilles Courteau became president of the QMJHL on February 13, 1986. The Hull Olympiques finished first overall in the regular season, winning their first Jean Rougeau Trophy, and won their first President's Cup, defeating the Drummondville Voltigeurs in the finals.
