1983–84 WHL season

The 1983–84 WHL season was the 18th season of the Western Hockey League (WHL). The Kamloops Junior Oilers won both the Scotty Munro Memorial Trophy for best regular season record and the President's Cup as playoff champions—defeating the Regina Pats in the championship series—both for the first time in club history.

The season was the first for the second incarnation of the New Westminster Bruins after the Nanaimo Islanders relocated from Vancouver Island prior to the season. The season saw Ray Ferraro set a league record with a 108-goal season for the Brandon Wheat Kings.
