Howth (/ˈhoʊθ/ HOATH; Irish: Binn Éadair, meaning “Éadar’s peak”)[2][3] is a village and outer suburb of Dublin, Ireland. The district occupies the greater part of the peninsula of Howth Head, forming the northern boundary of Dublin Bay. Originally just a small fishing village, Howth with its surrounding once-rural district is now a busy suburb of Dublin, with a mix of suburban residential development, wild hillside and heathland, golf courses, cliff and coastal paths, a small quarry and a busy commercial fishing port. The only neighbouring district on land is Sutton. Howth is also home to one of the oldest occupied buildings in Ireland, Howth Castle. It has been the location for many films.

Howth is also a civil parish in the ancient barony of Coolock.[4]
