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.
The Senators traded Percy LeSueur to the Ontarios for Fred Lake.
