Hunfrid of Prüm was a 9th-century Benedictine monk and prelate who served as the Bishop of Thérouanne and the Abbot of Saint-Bertin. Born into an aristocratic Carolingian family, he initially lived as a monk at Prüm Abbey, where he witnessed the burial of Emperor Lothair I. Following the death of his predecessor, he was appointed to the episcopacy in 856 by Pope Nicholas I. He is widely remembered for his leadership during the period of intense Norse raids in northern France, earning him a lasting reputation for pastoral courage.
