Crown–Indigenous Relations and Northern Affairs Canada

Crown–Indigenous Relations and Northern Affairs Canada (CIRNAC; French: Relations Couronne-Autochtones et des Affaires du Nord Canada) is the department of the Government of Canada responsible for Canada's northern lands and territories, and one of two departments with responsibility for policies relating to Indigenous peoples in Canada (the other being the Department of Indigenous Services, or ISC).

CIRNAC, along with ISC, were established to replace the Department of Indian Affairs and Northern Development (DIAND).

The department is overseen by two cabinet ministers, the Minister of Crown–Indigenous relations (whose portfolio includes treaty rights and land negotiations) and the Minister of Northern Affairs. Its headquarters is in Terrasses de la Chaudière, in downtown Gatineau, Quebec.
