The 1910 Allan Cup was the Canadian senior ice hockey championship for the 1909–10 season. The Allan Cup title was held by Queen's Golden Gaels and the Toronto St. Michael's Majors. Queen's won its league and a challenge before losing to Toronto, who successfully defended the title against Sherbrooke.

For the right to accept challenge from the champions of other leagues, the 1909 Allan Cup champions from Queen's University had to win the Ontario University Athletics final, or the winner would carry on for them. Played in Ottawa, Ontario.
