Largest island in Canada and fifth largest island in the world (183,810 sq mi [476,068 sq km]), lying between Greenland and the Canadian mainland. Located west of Baffin Bay and the Davis Strait, it is administered as part of Nunavut territory. It was probably visited by Norse explorers in the 11th century. It was sighted by Martin Frobisher during his search for a Northwest Passage (1576–78). It is uninhabited except for a few coastal settlements. The world's northernmost mines are at Nanisvik. In 1972 Auyuittuq National Park was created on the eastern coast.
