Gaudentius of Novara was a 4th-century Catholic priest and the first bishop of Novara. Born in Ivrea to a pagan family, he was converted to the Christian faith by Eusebius of Vercelli. Following the exile of Eusebius, Gaudentius was sent to Novara to assist the local church. He later received consecration as bishop from Simplician, the successor to Saint Ambrose, around 398 AD. Throughout his ministry, he was known for preaching and ordaining many new members of the clergy.
