Snape Island is an uninhabited island in Qikiqtaaluk Region, Nunavut, Canada. Located in Hudson Bay, it is a member of the Belcher Islands group. It closes Omarolluk Sound on its southwestern side. Rock Passage at its north end separates it from the Mukpollo Peninsula of Flaherty Island, and the Narrow Passage at its southeast end separates it from O'Leary Island.
Other islands in the immediate vicinity include Broomfield Island, Innetalling Island, and Walton Island.
The island is unrelated to the setting of the 1972 UK movie Horror on Snape Island by director Jim O'Connolly.
