Eugenius III of Toledo was a 7th-century archbishop and writer who served the see of Toledo from 647 until his death in 657. Born to a Goth named Evantius, he previously served as an archdeacon in Zaragoza. Although he was considered inexperienced in church administration, he was chosen by King Chindaswinth to succeed the previous archbishop. Despite having a frail constitution, he was a dedicated prelate who worked closely with Bishop Braulio and participated in several important ecclesiastical synods during his tenure.
