Cambridge Bay (Inuinnaqtun: Iqaluktuuttiaq Inuktitut: ᐃᖃᓗᒃᑑᑦᑎᐊᖅ; 2021 population 1,760; population centre 1,403) is a hamlet located on Victoria Island in the Kitikmeot Region of Nunavut, Canada. It is the largest of the two settlements on Victoria Island, the other being Ulukhaktok in the Northwest Territories. Cambridge Bay is named for Prince Adolphus, Duke of Cambridge, while the traditional Inuinnaqtun name for the area is Ikaluktutiak (old orthography) or Iqaluktuuttiaq (new orthography) meaning "good fishing place".
The traditional language of the area is Inuinnaqtun and is written using the Latin alphabet rather than the syllabics of the Inuktitut writing system. Like Kugluktuk, Bathurst Inlet and Umingmaktok, syllabics are rarely seen and used mainly by the Government of Nunavut.
