Exuperius of Bayeux was a 4th-century bishop who served as the first leader of the See of Bayeux from roughly 390 until 405. Also known as Spirius, he is recognized as a saint within the Catholic and Orthodox traditions. While some historical legends suggested he was a disciple of the 1st-century Saint Clement, modern scholars indicate he likely established the bishopric during the mid-fourth century, preceding the missionary work of the priest Saint Reverendus in the region.
