The Diocese of Angoulême is a Latin diocese of the Catholic Church in France. Originally erected in the 3rd century, the episcopal see is the Angoulême Cathedral. Comprising the département of the Charente, the diocese had traditionally been suffragan to the Archbishopric of Bordeaux, under the old régime as well as under the Concordat, but since 2002 is suffragan to the Archdiocese of Poitiers.
