Cornwallis Island is one of the Queen Elizabeth Islands, part of the Arctic Archipelago, in the Qikiqtaaluk Region of Nunavut in the Canadian Arctic. It lies to the west of Devon Island and at its greatest length is about 113 km (70 mi). At 6,995 km2 (2,701 sq mi) in size, it is the 96th largest island in the world, and Canada's 21st largest island. Cornwallis Island is separated by the Wellington Channel from Devon Island, and by the Parry Channel from Somerset Island to the south. Northwest of Cornwallis Island lies Little Cornwallis Island, the biggest of a group of small islands at the north end of McDougall Sound, which separates Cornwallis Island from nearby Bathurst Island.
Cape Airy is located at the island's southwestern extremity. Also on the southwestern coast, Griffith Island lies directly across from the island's only hamlet Resolute (Qausuittuq), separated by the 6.5 mi (10.5 km) wide Resolute Passage. The airport at Resolute acts as a communications hub for the central Arctic islands of Nunavut. This is Canada's second most northerly public community and has a population of 198 in 2016.
Cornwallis Island is also home to microbiological colonies known as hypoliths, from their tendency to take hold under ("hypo") stones ("lith").
