The 1972–73 QMJHL season was the fourth season in the history of the Quebec Major Junior Hockey League. The summer of 1972 saw the departure of the Saint-Jérôme Alouettes and the Verdun Maple Leafs from the league, reducing the circuit to eight teams. In an off-season lawsuit between the QMJHL and the OHA, the QMJHL gained a team, when the Montreal Junior Canadiens transferred leagues.
Michel Brière Memorial Trophy is first awarded to the league's most valuable player in honour of Michel Brière, who was killed in a car accident. Nine teams played 64 games each in the schedule. The Quebec Remparts finished first place in the regular season, and won the President's Cup, defeating the Cornwall Royals in the finals.
The Saint-Jérôme Alouettes cease operations.
The Verdun Maple Leafs cease operations.
The Montreal Junior Canadiens transfer from the Ontario Hockey Association to play in the QMJHL as the Montreal Bleu Blanc Rouge.
