Howth 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. It is also a civil parish in the ancient barony of Coolock. Originally just a small fishing village, Howth with its surrounding once-rural district is now a busy suburb of Dublin, with a mix of dense residential development and wild hillside. The only neighbouring district on land is Sutton.
