The 1914–15 Ottawa Senators season was the Ottawa Hockey Club's 30th season of play since its founding in 1883 (with some inactive years in the 1880s). After placing fourth in 1913–14, the Senators improved to win the NHA title, but lost the Stanley Cup 'World Series' playoff to the Vancouver Millionaires, played in Vancouver.
As the 1914 Final was held in Toronto, all three games in this series were played at the arena of the PCHA's champion in Vancouver, British Columbia. The Millionaires swept the best-of-five series in three games.
