The Parish of Raheny is the modern successor in the Roman Catholic Church to an early parish, in Raheny, a district of Dublin, Ireland, reputed to be a site of Christian settlement back to at least 570 A.D. Today's parish, within the Howth Deanery of the Roman Catholic Archdiocese of Dublin, comprises Raheny village and the central portion of the district, parts of which are also served by the parishes of Killester, Grange Park and Kilbarrack-Foxfield.
