The Ross Errilly Friary (Irish: Mainistir an Rois, often anglicised in 18th and 19th century sources as Rosserelly) is a medieval Franciscan friary located on the Black River about a mile to the northwest of Headford, County Galway, Ireland. It is a National Monument of Ireland and among the best-preserved medieval monastic sites in the country. Though usually referred to by locals as "Ross Abbey," this is not technically correct as the community never had an abbot.
