The 1915 Stanley Cup Finals was played from March 2226, 1915. The Pacific Coast Hockey Association (PCHA) champion Vancouver Millionaires swept the National Hockey Association (NHA) champion Ottawa Senators three games to none in a best-of-five game series. The finals were played in Vancouver, with games one, three and five played under PCHA rules. The Millionaires became the first team from the PCHA to win the Cup. This was the second Stanley Cup championship series between the champions of the NHA and the PCHA and the first held in a PCHA rink.

The Vancouver Millionaires (later known as the Vancouver Maroons) were a professional ice hockey team that competed in the Pacific Coast Hockey Association and the Western Canada Hockey League between 1911 and 1926. Based in Vancouver, British Columbia, they played in Denman Arena, the first artificial ice surface in Canada and the largest indoor ice rink in the world at the time it opened.The Millionaires/Maroons succeeded as PCHA champions six times (1915, 1918, 1921, 1922, 1923, 1924) and won the Stanley Cup once, in 1915, against the Ottawa Senators of the NHA.

Their jerseys were maroon, featuring a white V with "Vancouver" spelled down one side of the V and up the other. Hall of Famers Fred "Cyclone" Taylor, Mickey MacKay and Didier Pitre were among the most significant players to don the Millionaires/Maroons uniform in the team's history.

On October 1, 2010, the Vancouver Canucks president and management officially announced that the Vancouver Canucks had purchased the rights to logos, jerseys and trademarks of the Vancouver Millionaires. Since that time, the Canucks have worn Millionaires throwback uniforms on a few occasions, most notably on March 2, 2014 in the 2014 Heritage Classic against the Ottawa Senators.
