Howth ( HOHTH; Irish: Binn Éadair, meaning 'Éadar's peak') is an affluent peninsular village and outer suburb of Dublin, Ireland. The district as a whole occupies the greater part of the peninsula of Howth Head, which forms the northern boundary of Dublin Bay, and includes the island of Ireland's Eye, which holds multiple natural protection designations. Howth has been settled since prehistoric times, and features in Irish mythology. A fishing village and small trading port from at least the 14th century, Howth has grown to become a busy and affluent 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, and its estate.Howth is also a civil parish in the ancient barony of Coolock.

The Church of the Assumption, Howth is a Roman Catholic church in Howth, in Fingal in the historic County Dublin. The church is situated at the junction of Thormanby Road and Main Street, Howth, with St. Mary's Road, a short road joining the other two roads, behind. The roof is double pitched slate with decorative terracotta ridge tiles and cast iron rainwater goods. The walls are rockfaced granite with a limestone plinth, gargoyles and early Irish stone crosses.

Howth Lifeboat Station sits on the middle pier at Howth Harbour in the fishing village of Howth, on Howth Head, a peninsula located on the north side of Dublin Bay, in the administrative region of Fingal, historically County Dublin, on the east coast of Ireland. A lifeboat was first stationed at Howth in 1817 by the Corporation and Port of Dublin. Management of the station was transferred to the Royal National Lifeboat Institution (RNLI) in 1862. The station currently operates a Trent-class All-weather lifeboat, 14-33 Roy Barker III (ON 1258), on station since 2002, and the D-class (IB1) Inshore lifeboat Aideen Cresswell (D-796), on station since 2016.

The Harbour lighthouse in Howth is an historic aid to navigation situated on the East pier of the harbour. It was built in the early 19th century to help guide shipping into the newly constructed harbour, which acted as the terminus for the packet service between Ireland and England. In 1982 it was decommissioned and replaced by a modern pole light on an adjacent extension of the pier.

The Old Courthouse in Howth is a former place of worship that was subsequently used as a courthouse. It was built around 1845 and used as a place of worship for fishermen, then later used as a rent collection office by agents of Lord Howth. By 1870 it was used as a local courthouse and it continued as one until 1970. It is at the junction of Harbour Road and Church Street. It is a protected structure under Part IV of the Planning & Development Act 2000 and is a protected structure numbered RPS 567. It is part of the Howth Historic Core Architectural Statement of Character.It was due to be refurbished in early 2020 as a tourist centre.

Howth Head ( HOHTH; Ceann Bhinn Éadair in Irish) is a peninsula northeast of the city of Dublin in Ireland, within the governance of Fingal County Council. Entry to the headland is at Sutton while the village of Howth and the harbour are on the north-eastern face. Most of Howth Head is occupied by the Hill of Howth, though there are other regions, such as the tombolo at Sutton, extensive beaches on the northern shores, and small ones in other parts. The Baily Lighthouse is on the southeastern part of Howth Head. Nearby are the districts of Baldoyle and Portmarnock, and adjacent is the nature reserve of North Bull Island.

Howth Castle ( HOHTH) and estate lie just outside the village of Howth, County Dublin in Ireland, in the administration of Fingal County Council. The castle was the ancestral home of the line of the St Lawrence family (see: Earl of Howth) that had held the area since the Norman Invasion of 1180, and held the title of Lord of Howth until circa 1425, the Baron Howth to 1767, then Earl of Howth until 1909. The castle and estate are held since 1909 by their distaff heirs, the Gaisford-St Lawrence family. The estate includes much of the peninsula of Howth Head, including extensive heathland and much of Howth's cliff walks, with views over Dublin Bay, light woodland, and the island of Ireland's Eye. On the grounds near the castle are golf, pitch and putt and footgolf facilities, a former hotel, formal gardens and a pond, rhododendron walks - and several small streams pass through the estate. In October 2018, the family announced their agreement to sell the castle, demesne and Ireland's Eye to the Tetrarch investment group who intended to redevelop the hotel and course as a luxury resort. A 7-acre portion of the site zoned for residential development close to the castle gate was sold onwards by Tetrarch to Glenveagh Homes for €14m after the sale closed. Glenveagh's interim financial report notes they intend to build 200 apartments on the site with first deliveries in 2023.

The Ben of Howth ( HOHTH; Irish: Beann Éadair ) is a hilly area on Howth Head, adjacent to the 171 metre high Black Linn, the peninsula's highest point.

Ireland's Eye (Irish: Inis Mac Neasáin) is a small long-uninhabited island off the coast of County Dublin, Ireland. Situated directly north of Howth village and harbour, the island is easily reached by regular seasonal tourist boats, which both circumnavigate it and drop off day trippers. There is a yacht anchorage to the north of it, and kayakers also land. The island is formed from quartzite and greywackes, and some sandstone, and has soils based on glacial drift. It is home to nationally significant bird populations, notably of guillemots, razorbills, kittiwakes and cormorants, as well as gulls, and also including modest numbers of puffins and peregrine falcons. There is a colony of grey seals, and surrounding waters also host harbour seals and harbour porpoise, while on land there are rats and rabbits. There is a range of plants, including some rare species and some specific to vegetated cliffs. The island has been essentially uninhabited for centuries but holds the ruins of an early church, and a Martello tower. The Eye is the basis for both a Special Area of Conservation and a Special Protection Area, and is incorporated within the Howth Special Amenity Area, and the Dublin Bay Biosphere, among other designations. It is part of Fingal for administrative purposes, having been moved to County Dublin along with Howth, Sutton, Baldoyle and Kilbarrack, from the jurisdiction of Dublin. The island was for centuries a possession of the archdiocese of Dublin, and then a component of the Howth Estate. It was sold to the Tetrarch investment group as part of a deal finalised in 2019.
