Winnoc was a 7th-century Benedictine abbot, likely of Welsh noble descent, who lived in the pays de Dol and later Flanders. After moving to Flanders with three companions, he established a monastery at Sint-Winoksbergen and later founded a priory at Wormhout, which served as a significant missionary center. In his later years, he was noted for his ability to perform labor, such as grinding grain, through divine assistance. He died around 716 or 717 at what is now known as St Winnoc's Abbey in Bergues.
