The Lester Patrick Cup was the championship trophy of the Pacific Coast Hockey League and the Western Hockey League (WHL) from 1949 to 1974. Originally known as the President's Trophy, the trophy was renamed in 1960 to honour Pacific Coast Hockey pioneer Lester Patrick following his death on June 1 of that year.

The Lester Patrick Cup was retired following the demise of the WHL, and is on display at the Hockey Hall of Fame in Toronto.

The Pacific Coast Hockey League was an ice Hockey minor league with teams in the western United States and western Canada that existed in several incarnations: from 1928 to 1931, from 1936 to 1941, and from 1944 to 1952.

The final incarnation of the league was managed by Hockey Hall of Fame member Al Leader, and grew out of combining teams from the Southern California Hockey League and the Northwest International Hockey League. The PCHL was founded as an amateur loop, partly because the National Hockey League recognized Pacific Coast Hockey Association (PCHA) founder Lester Patrick as the territorial rights holder for professional Hockey in Vancouver, Portland and Seattle. In 1948, however, the ten team league voted to turn pro, and was recognized as such by the NHL.

In 1951, having dwindled to a six team league, the PCHL merged with the Western Canada Senior Hockey League, adding three new franchises on the Canadian prairies. Following the merger of the PCHL with the Western Canada Senior Hockey League in 1951, the league renamed itself the Western Hockey League for the 1952-53 season.

The PCHL championship trophy was the President's Cup.

The championship trophy of the WHL was the Lester Patrick Cup.
