The Diocese of Autun (–Chalon-sur-Saône–Mâcon–Cluny) (Latin: Dioecesis Augustodunensis (–Cabillonensis–Matisconensis–Cluniacensis); French: Diocèse d'Autun (–Chalon-sur-Saône–Mâcon–Cluny)), more simply known as the Diocese of Autun, is a Latin Church diocese of the Catholic Church in France. The diocese comprises the entire Department of Saone et Loire, in the Region of Bourgogne.
The diocese was suffragan to the Archdiocese of Lyon under the Ancien Régime, and the Bishop of Autun held the post of Vicar of the Archbishop. The bishopric of Chalon-sur-Saône (since Roman times) and (early medieval) bishopric of Mâcon, also suffragans of Lyon, were united to Autun after the French Revolution by the Concordat signed by First Consul Napoleon Bonaparte and Pope Pius VII. For a short time, from 1802 to 1822, the enlarged diocese of Autun was suffragan to the Archbishop of Besançon. In 1822, however, Autun was again subject to the Archbishop of Lyon. The diocese of Autun is now, since 8 December 2002, suffragan to the Archbishop of Dijon. The current bishop of Autun is Benoit Rivière.
