The Pacific Coast Hockey Association (PCHA) was a professional men's ice hockey league in western Canada and the western United States, which operated from 1911 to 1924 when it then merged with the Western Canada Hockey League (WCHL). The PCHA was considered to be a major league of ice hockey and was important in the development of the sport of professional ice hockey through its innovations.
