Cumberland Sound (Inuit: Kangiqtualuk) (other names: Cumberland Straits; Hogarth Sound; Northumberland Inlet) is an Arctic waterway in Qikiqtaaluk Region, Nunavut, Canada. It is a western arm of the Labrador Sea located between Baffin Island's Hall Peninsula and the Cumberland Peninsula. It is approximately 250 km (160 mi) long and 80 km (50 mi) wide.
Small islands litter the stretch of water which was formed from glacial activity and meltwater produced from the receding glacier.
The only settlement located on the shore of the sound on the Cumberland Peninsula is Pangnirtung. John Davis, the English explorer, went part way up the sound in 1585.
The bay is home to the Cumberland Sound beluga whale, a species known to reside year-round in the sound, with summers spent at the northern end. As well as ringed, bearded, harp, harbour and hooded seals, there are Arctic char, Greenland halibut, and other fish. Birds such as gulls, ducks, and geese also migrate and spend the spring and summer in Cumberland Sound, and ptarmigan and ravens remain year-round.
