Vincent of Lérins (Latin: Vincentius; died c. 445) was a Gallic monk and author of early Christian writings. One example was the Commonitorium, c. 434, which offers guidance in the orthodox teaching of Christianity. Suspected of semipelagianism, he opposed the Augustinian model of grace and was probably the recipient of Prosper of Aquitaine's Responsiones ad Capitula Objectionum Vincentianarum. His feast day is celebrated on 24 May.
