Saint Austol (Welsh: Austel; Latin: Austolus) was a 6th-century Cornish holy man who lived much of his life in Brittany. He was a friend of Saint Méen, who founded the Saint-Méen Abbey in Brittany. Méen is said to have been his godfather. The parish and town of St Austell in Cornwall is named in his honour. He is regarded as a saint and is honoured with a Breton feast day on 28 June and a Cornish feast day on the Thursday of Whitsun. According to tradition, Austol died within a week after the death of Méen.
