Porcarius (died c. 732), known as Saint-Porchaire in French, was a Benedictine abbot who governed the Abbey of Lérins, off the coast of the French Riviera, (now known as Île de Saint-Honorat, as the monastery was founded by Honoratus of Arles) at a time when the monastery included over 500 monks. According to tradition, around the year 732, Porcarius was warned by an angel in a vision that the abbey was about to be attacked by barbarians.
