Tuktoyaktuk, or Tuktuyaaqtuuq IPA: [təktujaːqtuːq], is an Inuvialuit hamlet located near the Mackenzie River delta in the Inuvik Region of the Northwest Territories, Canada, at the northern terminus of the Inuvik–Tuktoyaktuk Highway. One of six Inuvialuit communities in the Inuvialuit Settlement Region, it is commonly referred to by its first syllable, Tuk. It lies north of the Arctic Circle on the shores of the Arctic Ocean, and is the only place on the Arctic Ocean connected to the rest of Canada by road. Known as Port Brabant after British colonization, in 1950 it became the first Indigenous settlement in Canada to reclaim its traditional name.

The Inuvialuit or Western Canadian Inuit are Inuit who live in the western Canadian Arctic region. They, like all other Inuit, are descendants of the Thule who migrated eastward from Alaska. Their homeland – the Inuvialuit Settlement Region – covers the Arctic Ocean coastline area from the Alaskan border, east through the Beaufort Sea and beyond the Amundsen Gulf which includes some of the western Canadian Arctic Islands, as well as the inland community of Aklavik and part of Yukon. The land was demarked in 1984 by the Inuvialuit Final Agreement.
