The 1911 Allan Cup was the Canadian senior ice hockey championship for the 1910–11 season. The defending champion Toronto St. Michael's Majors were stripped of the title by default to the Winnipeg Victorias. The Victorias then defeated the Kenora Thistles in a challenge to hold the title. It was the third season of play for the Allan Cup.

The Allan Cup is the trophy awarded annually to the senior ice hockey champions of Canada. It was donated by Sir Montagu Allan of Ravenscrag, Montreal, and has been competed for since 1909. The current champions are the Dundas Real McCoys, who captured the 2023 Allan Cup in Dundas, Ontario.
