The Municipality of Baie-James (French: Municipalité de Baie-James) was a municipality in northern Quebec, Canada, which existed from 1971 to 2012. Located to the east of James Bay, Baie-James covered 297,332.84 square kilometers of land, making it the largest incorporated municipality in Canada — only eight unorganized territories were larger. Its territory almost entirely (about 98%) covered the administrative region of Jamésie, although it contained less than five percent of the population.
