Lancaster Sound

Lancaster Sound (Inuktitut: ᑕᓪᓗᕈᑎᐅᑉ ᐃᒪᖓ, romanized: Tallurutiup Imanga) is a body of water in the Qikiqtaaluk Region, Nunavut, Canada. It is located between Devon Island and Baffin Island, forming the eastern entrance to the Parry Channel and the Northwest Passage. East of the sound lies Baffin Bay; to the west lies Viscount Melville Sound. Further west, a traveller would enter the M'Clure Strait before heading into the Arctic Ocean.

The Inuit and their predecessors in the region, the Paleo-Eskimos, have relied for hundreds, perhaps thousands of years, on the sound's abundant natural wealth for food, clothing and shelter. Today, residents of the three Nunavut communities of Pond Inlet, Arctic Bay, and Resolute continue this tradition, depending on their waters for their economic and cultural well-being.
