The 1976–77 WCHL season was the 11th season of the Western Canada Hockey League. It featured twelve teams and a 72-game regular season. The Brandon Wheat Kings won their first regular season title, posting 54 wins on the season. However, in the playoffs the New Westminster Bruins continued their run of dominance and won their third consecutive President's Cup, defeating the Wheat Kings in the championship series. The Bruins advanced to the 1977 Memorial Cup tournament, and there they secured their first Memorial Cup title.
The season was the first for the Portland Winter Hawks, who became the league's first American-based club when the charter Edmonton Oil Kings relocated to Portland, Oregon prior to the season. The Winnipeg Clubs also changed their name to the Monarchs.
