Loup de Bayeux was a 5th-century prelate who served as the bishop of Bayeux between approximately 440 and 470. Born into a pagan family in Bayeux, he was converted to Christianity by Rufinien, the third bishop of the city. Legend suggests he received his name from a young child and was elevated to the episcopacy by Sylvester, the archbishop of Rouen. During his ministry, he was noted for his religious leadership and for performing miracles, such as restoring sight to the blind.
