Its current name was established in 2005.

When the diocese was founded in 1963 as the Diocese of Hull, it had as its cathedral, Holy Redeemer Church in Hull. In 1982, when it was renamed as the Diocese of Gatineau–Hull, it had two co-cathedrals, St. John Vianney Church in Gatineau and St. Joseph Church in Hull. In 2005, when it became the Archdiocese of Gatineau, it ceased to have co-cathedrals as St. Joseph Cathedral became the cathedral for the whole archdiocese.
