Mothel Abbey is a former Augustinian monastery and National Monument located in County Waterford, Ireland.

[5] It was refounded by the Augustinian Canons Regular after 1140, and they controlled a large region of central County Waterford.

[6] The last abbot, Edmund Power, surrendered the abbey on 7 April 1540 as part of the Dissolution of the Monasteries.

This led to a prolonged conflict with Patrick Comerford, bishop of Waterford and Lismore and Vicar General of the Order of Canons Regular of St. Augustine, who eventually convinced Madan before his death in 1645.

In the surviving south wall are two windows, one completely disfigured, the other consisting of two plain Gothic lights separated by a limestone mullion, and the arches formed of two stones each.
