The bishopric of Auxerre (Lat. dioecesis Autissiodorensis) is a former French Roman Catholic diocese. Its historical episcopal see was in the city of Auxerre in Burgundy, now part of eastern France. Currently the non-metropolitan Archbishop of Sens, ordinary of the diocese of Sens and Auxerre, resides in Auxerre.

The Gestes des évêques d'Auxerre, written about 875 by the canons Rainogala and Alagus, and continued later down to 1278, gives a list of bishops which, save for one detail, Louis Duchesne regards as accurate; but the chronological data of the Gestes ('deeds') seem to him to be very arbitrary for the period prior to the 7th century. No other church of France glories in a similar list of bishops honoured as saints; already in the Middle Ages this multiplicity of saints was remarkable.
St. Peregrinus (Pélérin 'pilgrim') was the founder of the see; according to the legend, he was sent by pope Sixtus II and was martyred under Emperor Diocletian in 303 or 304.

On November 29, 1801 the bishopric was suppressed, on October 7, 1817 restored, in 1821 again suppressed. On June 3, 1823 it was united (having no separate titular bishop) to the diocese (soon after archbishopric again) of Sens, which lost its Metropolitan status in 2006 to become part of the Ecclesiastical Province of the archbishopric of Dijon.
The Cathedral of Auxerre, completed in 1178, contains numerous sculptures in the Byzantine style.
