The Baie-James (French pronunciation: [bɛ dʒɛmz]) was a former municipality in northern Quebec, Canada, which existed from 1971 to 2012.

Located to the east of James Bay, Baie-James covered 297,332.84 km2 (114,800.85 sq mi) of land, making it the largest incorporated municipality in Canada — only eight unorganized territories were larger.

It managed the territory of the James Bay and Northern Quebec Agreement between the 49th and 55th parallel, with the exception of the Cree Category 1 lands and the enclaves of Chapais, Chibougamau, Lebel-sur-Quévillon and Matagami.

It became a municipality of a special type directed by the mayors of the four enclave towns, as well as the chairpersons of the local community councils of Radisson, Valcanton and Villebois.

Under the terms of the Agreement on Governance in the Eeyou Istchee James Bay Territory of July 24, 2012, the municipality ceased to exist and was replaced by a new regional government called Eeyou Istchee James Bay Territory.
