The Diocese of Moosonee is a Roman Catholic diocese in northern Ontario which administers Catholic business in the area. It was created from portions of the Diocese of Haileybury and the Apostolic Vicariate of Northern Ontario in 1938 as the Apostolic Vicariate of James Bay. On July 13, 1967, the Vicariate was promoted to the Diocese of Mossonee but on May 31, 2007, the Diocese lost all of its Quebec territory to the Diocese of Amos. The Diocese of Mossonee was disbanded by the Roman Catholic Church on December 3, 2018. Its territory was transferred to the Diocese of Hearst-Mossonee.
During the Residential School System, St. Anne’s Residential School (Fort Albany) operated within the boundaries of the Diocese of Moosonee. While the Diocese did not run the day-to-day operations of the school, the missionary congregations often worked with diocesan authorities. In the Indian Residential School Settlement Agreement (IRSSA), the Diocese is listed as La Corporation Episcopale Catholique de la Baie James.
