The minister of Intergovernmental Affairs (French: Ministre des Affaires intergouvernementales) is the Minister of the Crown in the Canadian Cabinet who is responsible for the federal government's relations with the governments of the provinces and territories of Canada.

The Minister of Intergovernmental Affairs does not head a full-fledged department, but rather directs the Intergovernmental Affairs Secretariat within the Privy Council Office, and ministers have often been assigned additional duties.

[6] From 1991 to 1993, the Minister responsible for Constitutional Affairs served a similar role focused on intergovernmental negotiation of a package of constitutional reforms.

The resulting package, the Charlottetown Accord, was defeated in a 1992 referendum.

Several provincial governments, such as Ontario, Manitoba and Quebec, have also created homologous ministerial positions responsible for relations with other provinces and the federal government.
