Ellesmere Island is Canada's northernmost and third largest island, and the tenth largest in the world. It comprises an area of 196,235 square kilometres (75,767 sq mi), slightly smaller than Great Britain, and the total length of the island is 830 km (520 mi).
Lying within the Arctic Archipelago, Ellesmere Island is considered part of the Queen Elizabeth Islands. Cape Columbia at 83°06′is the most northerly point of land in Canada. (The most northerly point of land on Earth is the nearby Kaffeklubben Island of Greenland).
The Arctic Cordillera mountain system covers much of Ellesmere Island, making it the most mountainous in the Arctic Archipelago. More than one-fifth of the island is protected as Quttinirpaaq National Park.
In 2016, the population of Ellesmere Island was recorded at 191. There are three settlements: Alert, Eureka, and Grise Fiord. Ellesmere Island is administered as part of the Qikiqtaaluk Region in the Canadian territory of Nunavut.
