The Roman Catholic Archdiocese of Bordeaux, the full name of which since 20 November 1937 has been the Archdiocese of Bordeaux-Bazas, is an archdiocese of the Latin Rite of the Roman Catholic church in France. The episcopal seat is located in Bordeaux, Aquitaine. It was established under the Concordat of 1802 by combining the ancient Diocese of Bordeaux (diminished by the cession of part to the Bishopric of Aire) with the greater part of the abolished Diocese of Bazas.
