The 1974–75 WCHL season was the ninth season of the Western Canada Hockey League (WCHL). It featured twelve teams playing a 70-game regular season, an increase from 68. The Victoria Cougars topped the regular season standings with 47 wins. In the playoffs, the New Westminster Bruins defeated the Saskatoon Blades in a seven-game championship series to win the President's Cup. With the win, the Bruins earned a berth at the 1975 Memorial Cup tournament, in which they lost the final to the Toronto Marlboros, who captured their record seventh national title.
During the 1975 Memorial Cup tournament, officials from the WCHL and the other two Canadian major junior leagues—the Ontario Major Junior Hockey League and the Quebec Major Junior Hockey League—announced the formation of the Canadian Major Junior Hockey League as an umbrella organization for major junior hockey.
