Molana Abbey (Irish: Mainistir Mhaolanfaidh) is a 6th-century Abbey located on the south coast of Ireland in the Diocese of Waterford and Lismore, near Youghal. The abbey lies on an island in the River Blackwater. The monks of the monastery helped co-edit Collectio canonum Hibernensis in the 8th century. It came under the control of the Augustinian canons in the 12th century before being seized by the English Crown during the Reformation and gradually falling into ruin.
