The Parish of St. John the Baptist, the Church of Ireland Parish of Clontarf, Dublin is a religious community located on the north shore of Dublin Bay, bounded by the Parishes of North Strand to the west, Coolock to the north, and Raheny to the east (the latter two are in a Union). The Parish Church is situated on Seafield Road, approximately 2+1⁄2 miles (4.0 km) from the churches of each of the adjoining parishes. It was built in 1866 to replace an earlier church some 200 metres away on Castle Avenue, on the edge of the grounds of Clontarf Castle.
