The 1914–15 PCHA season was the fourth season of the professional men's ice hockey Pacific Coast Hockey Association league. Season play ran from December 8, 1914, until March 9, 1915. The schedule was made for each team to play 18 games, but like the previous three seasons, one game was cancelled. The Vancouver Millionaires club were the PCHA champions. After the season the club faced off against the Ottawa Senators, NHA champions for the Stanley Cup, winning the series and becoming the first west-coast team to win the Cup.
The franchise of the New Westminster Royals was transferred to Portland, Oregon, and renamed the "Rosebuds." The league established a "farm system" called the Boundary Hockey League in the British Columbia towns of Grand Forks, Greenwood and Phoenix.
