Knocklyon (Irish: Cnoc Lín)[2][3] is a suburb of Dublin in Ireland. It is on the southwest of the city, and just north of the foothills of the Dublin Mountains.


The M50 motorway divides Knocklyon, with most of the suburb lying on the east of the motorway. Housing estates to the east include Beverly, Dargle Wood, Delaford, Idrone, Knockaire, Orlagh, Templeroan, and Woodfield. To the west of the M50 are estates such as Castlefield Manor, Glenlyon, Glenvara Park, and Woodstown. These are linked to the rest of Knocklyon by a footbridge and by Junction 12 of the motorway.


The population figure cannot be isolated from published census data as Knocklyon is composed of Firhouse-Knocklyon district electoral division (DED) (population 3,602 in 2011), plus unpublished fractions of Ballyboden DED (5,085), and Firhouse-Ballycullen DED (7,773).[4]


The area is in the Dublin South Dáil Éireann constituency, and in the Rathfarnham local electoral area for county council elections.[5][not in citation given]


Local amenities include a supermarket, post office, credit union, a Catholic parish church and a community centre, which opened in 1989. The area has a number of open spaces within the residential estates, playing pitches for Ballyboden St. Enda's GAA Club and Knocklyon United Football Club, as well as a scouting group and the South Dublin Model Railway Club, all of which have their own premises. A division of the St. John Ambulance was established in September 2010 which provides first aid training and services in the community. There are two local pubs.


St. Colmcille's national school opened in September 1976.[citation needed] Gaelscoil Chnoc Liamhna is an Irish language primary school that was established in September 1996 with 36 pupils. The school now teaches 234 children.[6] St. Colmcille's Community School (formerly Knocklyon Community School)[7] has 700 secondary students and opened in September 2000.[citation needed]


The Parish of Knocklyon was established in October 1974. It was placed under the patronage of St. Colmcille and is run for the Dublin Archdiocese by the Carmelites. The Parish church opened in April 1980. The Iona Pastoral Centre near the church caters for a wide range of activities[clarification needed] and was formally opened in 2000.

The Knocklyon Church of Christ is an autonomous Christian congregation on the Knocklyon Road, near Gaelscoil Chnoc Liamhna.
