Juvenal of Narni was a 4th-century bishop who served as the first leader of the church in Narni, Italy. Born in Carthage, he was reportedly ordained by Pope Damasus I. While historical records of his life are sparse, he is recognized as a confessor in several traditions. Some historical accounts, including writings by Gregory the Great, have referred to him as a martyr, a title sometimes applied to bishops regardless of the specific circumstances of their death.
