The 1922–23 PCHA season was the 12th season of the professional men's ice hockey Pacific Coast Hockey Association league. Season play ran from November 13, 1922, until March 2, 1923. The Vancouver Maroons club would be regular-season PCHA champions, and won the play-off with Victoria Aristocrats.
The league finally dropped the position of rover, adopting the six-man hockey of the National Hockey League (NHL), eleven years after the National Hockey Association (NHA) dropped it.
The Vancouver Millionaires were renamed the Maroons, and the Victoria Aristocrats were renamed the Cougars. The season was increased to 30 games per team, including eight games against Western Canada Hockey League (WCHL) teams.
Vancouver acquired Corbett Denneny from Toronto for Jack Adams and signed Frank Boucher from Ottawa.
Frank Fredrickson had an outstanding season, scoring 41 goals in thirty games. Cyclone Taylor made the final appearance of his career on December 8 at Victoria.
