The Inuvialuit Settlement Region, abbreviated as ISR (Inuinnaqtun: Inuvialuit Nunangit Sannaiqtuaq – INS; French: Région désignée des Inuvialuit – RDI), located in Canada's western Arctic, was designated in 1984 in the Inuvialuit Final Agreement by the Government of Canada for the Inuvialuit people. It spans 90,650 km2 (35,000 sq mi) of land, mostly above the tree line, and includes several subregions: the Beaufort Sea, the Mackenzie River delta, the northern portion of Yukon ("Yukon North Slope"), and the northwest portion of the Northwest Territories. The ISR includes both Crown Lands and Inuvialuit Private Lands.
