Blackhawks–Blues rivalry

The Blackhawks–Blues rivalry is a National Hockey League (NHL) rivalry between the Chicago Blackhawks and the St. Louis Blues. Since the 1970–71 season (excluding the 2020–21 season), the two teams have been in the same division. It is the most intense rivalry in terms of penalty minutes and fighting, and at the height of the rivalry during the Norris Division days, it was common to go to a Chicago versus St. Louis game and see a brawl break out.

Since the move of the Detroit Red Wings to the Eastern Conference, this rivalry is considered the top divisional rivalry for both teams.
