Killiniq Island

Killiniq Island is a remote island in southeastern Nunavut and northern Newfoundland and Labrador, Canada. Located at the extreme northern tip of Labrador between Ungava Bay and the Labrador Sea, it is notable in that it contains the only land border between Nunavut and Newfoundland and Labrador. Most other islands off the northern coast of Quebec and Labrador belong exclusively to Nunavut. Some cartographic sources do not correctly show the island's geopolitical boundaries; for instance, the Commission de toponymie du Québec seems to show it as belonging to Quebec.

The northernmost point of Newfoundland and Labrador is Cape Chidley on the island. The largest identifiable land mass is the Torngat Mountains, part of the Arctic Cordillera, which proceed from the north to the south of the island.
