Kilternan (Irish: Cill Tiarnáin, meaning "Church of Tiarnán") is a village in County of Dún Laoghaire-Rathdown, in the foothills of the Dublin Mountains south of Dublin, near the border with County Wicklow.
Kilternan's most notable buildings are the Church of Ireland Parish Church of Kilternan which dates from 1826, the timber-built Catholic Church of Our Lady of the Wayside (Blessed and Dedicated on 14 July 1929), or 'The Blue Church' as it is known locally after its Marian colour, and the Golden Ball, or Palmers, pub which has been closed since June 2012 These names are joined at the local soccer club, Wayside Celtic whose ground is known as The Golden Ball. Kilternan is also home to a rugby club, De La Salle Palmerston, known locally as Salmo whose ground is known as Kirwan Park and is located at the northern end of the village.
Kilternan lacks a traditional village centre or 'Main Street'. It is the location of Ireland's only (artificial) ski slope.
Spelling of the name 
Road signs are somewhat confused regarding the correct spelling of the name of the area. For example; signs on the M50 motorway (Junction 15) call it Kilternan while signs at the junction on the adjoining roads refer to "Kiltiernan", even though both sets were erected at roughly the same time. Local government documents and ordnance survey maps refer to Kiltiernan while many local people spell the name without the "i". Locally, Kilternan is the most acceptable form.
Kilternan has an VEC or adult education center and well as a two National Primary schools located in close proximity to each of the villages two churches. The primary school at the southern end of Kilternan is called "Our Lady of the Wayside". while the primary school at the northern end of Kilternan is called the "Kilternan Church of Ireland Primary School". As of 2012 there are over 300 pupils in each of the schools.
