Felix (d. 303) was a bishop of Thibiuca in Africa who was martyred during the Great Persecution under the Roman emperor Diocletian alongside Audactus, Fortunatus, Januarius, and Septimus. Felix is said to have resisted the command of the local magistrate Magnillian (Latin: Magnillianus) to surrender his church's copies of the Christian scriptures. Felix was formerly honored as the patron saint of Venosa.
