Ardagh (Irish: Ardach) is a civil parish and townland in County Mayo, located slightly to the southwest of Ballina. The parish takes its name from an ancient ecclesiastical site, which was either a church or a small monastery, and is derived from "Ard Achadh", which means high ground. The earliest record of the first church in Ardagh is in an 1198 epistle issued by Pope Innocent 3rd.
