Eeyou Istchee James Bay (French: Eeyou Istchee Baie-James, Cree: ᐄᔨᔨᐤ ᐊᔅᒌ ᒉᐃᒥᔅ ᐯᐃ iiyiyiw aychii cheimiy pei) is a local municipality in the Jamésie (TE) in administrative region of Nord-du-Québec. Located to the east of James Bay, Eeyou Istchee James Bay covers 283,123.42 km (109,314.56 sq mi) of land, making it the largest incorporated municipality in Canada — only eight unorganized territories are larger. Its territory covers almost entirely the Equivalent territory of Jamésie.

The hydroelectric power plants of the La Grande Complex are all located within the municipal boundaries of Eeyou Istchee James Bay, making the municipality strategically important to Quebec's energy policy. Other important economic sectors are mining, softwood logging, forestry, and tourism.

The municipality of Baie-James was created in 1971 and was run by the board of directors of the Société de développement de la Baie James. 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.

In December 2001, the municipal council was reformed. 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. An eighth seat was reserved for a representative coming from the non-urban territory. The municipality gained additional authority and could exert certain powers as a regional county.

On July 24, 2012, the Quebec government signed an accord with the Cree (Agreement on Governance in the Eeyou Istchee James Bay Territory between the Crees of Eeyou Istchee and the Gouvernement du Québec) which resulted in the replacement of the municipality of Baie-James by the municipality of Eeyou Istchee James Bay. The agreement came into force on January 1, 2014, and is designed to give the Cree expanded powers over lands and resources outside of the Cree municipalities and associated reserved land. The new government consist of Cree and Baie-James residents each having an equal number of votes within the Eeyou Istchee James Bay Regional Government.
