Euphronius was a 6th-century cleric who served as the Bishop of Tours from 555 to 573. Born into a family of senatorial rank, he was a priest in Tours before being elected to the bishopric by the clergy and the local people following a vacancy. He was a relative of Gregory of Tours and maintained friendships with figures such as Venantius Fortunatus. During his eighteen-year tenure, he navigated significant political and religious challenges within the Frankish kingdoms.
