Nectarius of Autun was a 6th-century bishop who led the diocese of Autun from 540 until his death. A contemporary of Saint Germain of Paris, he was an active participant in the ecclesiastical affairs of his time, notably attending the Fifth Council of Orléans in 549. During his leadership, the first cathedral in Autun was consecrated, and he played a significant role in establishing religious connections between his region and other major Christian centers like Milan.
