Sutton (Irish: Cill Fhionntain, meaning 'Fintan's cell or church')[1] is a residential suburb on the Northside of Dublin, Ireland.

The first recorded mention of Sutton in reference to the area is from around 1228–48, noted in the Calendar of Archbishop Alen's Register; it is likely linked to a person of Norman origin.

The station lies on the Howth branch of the commuter rail network and is served by the Dublin Area Rapid Transit (DART) system.

[7]: 8  Carrickbrack Stream rises between Shielmartin Hill and Dun Hill near Howth Golf Course, and flows, meeting minor tributaries, roughly parallel to Carrickbrack Road, coming to the shore at the south-western end of the strand,[7]: 8  while Santa Sabina Stream comes from the central area of the Howth (Deer Park) Estate, and runs in culvert past the Offington housing estate and through the grounds of Santa Sabina Dominican Convent, reaching the sand around 150m north of the mouth of the Carrickbrack,[7]: 8  with concrete framing and a guard rail.

The Santa Sabina outfall, in front of Saint Fintan's Roman Catholic church, sometimes flows very actively but is notably sometimes covered by sand, which is then cleared by Fingal County Council staff.

There is one main commercial area, with a Supervalu store (previously a Superquinn) supermarket, under that chain's HQ, which in turn had replaced the local cinema), the Marine Hotel, a post office, and other banking, dining and retail operations.

[12] The local soccer club is Howth Celtic, with grounds located opposite St.Fintan's primary school on Carrickbrack Road.

There is a local scout group which meets in St. Mary's Church of Ireland Parish Hall in Howth.

One of the area's oldest buildings, the fifteenth century Corr Castle, is located at Sutton North near the Howth Road entrance to Offington housing estate.

Also located in Red Rock is Sutton Castle, the former home of the Jameson family, and later became the residence of Belgian businessman Albert Luykx, made famous during the Irish arms trial.

[15] The old tram shed which was used by the Hill of Howth Tramway is located near Sutton Station, but is now a private residence which is part of a modern housing development.

[16] The Luí na Gréine (English:Sunset) granite standing stone monument is located on the seaside pathway at Sutton strand and was designed by Cliodhna Cussen and erected in the mid-2000s.
