Blanchardstown (Irish: Baile Bhlainséir) is a large suburb of Dublin in Fingal, Ireland, located 10 km north-west of the city centre. It is within the historical barony of Castleknock, the Dublin 15 postal area and the Dublin West electoral constituency. It is largest urban area in the county. The 2011 Census recorded a population of 68,156 in Blanchardstown and its immediate environs.
Blanchardstown has grown up alongside its smaller neighbouring town, Castleknock. Both towns shared a common history until well into the 19th century, when their development diverged. The name Blanchardstown comes from the Blanchard family, who were granted their estate some time between 1250 and 1260. The name 'Blanchard' is thought to come from the old French word blanch, meaning white, and could refer to white or fair hair. The townland has an area of over 454 acres.
Blanchardstown was a rural village in western County Dublin until the late 1960s, when the first housing estates began to be developed. Blanchardstown developed in tandem with neighbouring settlement Castleknock, both of which grew rapidly from the early 1970s to the present. During the 1970s/80s, the village became subsumed into the suburban fabric of Dublin. The Institute of Technology, Blanchardstown (ITB) was established in 1999.
A criminal gang from Blanchardstown became notorious as "The Westies"; their leaders were killed in Spain in 2004.
In the 19th century, the Roman Catholic parish of Blanchardstown encompassed much of the area now within the Dublin 15 postal district. Following the relaxation of the Penal Laws, it became possible for the Catholic adherents to consider the construction of additional churches and to repair the existing stock of religious buildings. Church authorities used the opportunity to implement the Tridentine reform which saw the parish as the basic unit of ecclesiastical organisation and the parish priest as the central figure within the parish.
The new parish priest of Blanchardstown in 1839, Fr Michael Dungan, oversaw the construction of a number of new churches, which are today independent parishes in their own right, and invited a number of religious communities to provide for the education of Catholic children. St Brigid's Church, Blanchardstown – not to be confused with a church of the Church of Ireland in nearby Castleknock – was constructed in 1837 upon the foundation of a church that had been built prior to 1731. It is the Mother church of 12 other churches constituted out of the parish over the following 156 years. They are:
- Chapelizod - "Nativity of the Blessed Virgin Mary" (separated from Blanchardstown 1883)
- Navan Road - "Our Lady Help of Christians" (separated from Chapelizod 1953)
- Castleknock - "Our Lady Mother of the Church" (separated from Blanchardstown 1976)
- Corduff - "St Patrick's Church" (separated from Blanchardstown 1976)
- Huntstown - "Church of the Sacred Heart of Jesus" (separated from Blakestown 1981)
- Littlepace - "Chapel of Ease, Mary, Mother of Hope" (in the process of development since 2002)
- Hartstown - "St Ciarán' Church" (separated Blanchardstown 1979)
- Mulhuddart / Lady's Well - "St Luke, the Evangelist" (separated from Blanchardstown 1993)
Blanchardstown is just outside Dublin's M50 motorway ring road, slightly to the north of the tolled crossing of the River Liffey. The core of the suburb is the townland of the same name. It is bordered to the east by the suburb of Castleknock, to the west by Clonsilla/Ongar, to the north by Tyrellstown/Hollystown and to the south and south east by Porterstown/Diswellstown. The Royal Canal and the Dublin-Sligo railway line pass along the southern edge of Blanchardstown proper from east to west.
For the purposes of elections to Fingal County Council, the village is split between two local electoral areas (LEAs). They are Castleknock (4 councillors returned) and Mulhuddart (5 councillors returned).
There are three Irish Rail train stations in the Blanchardstown area at Castleknock, Coolmine and Clonsilla which connect to the city centre at Connolly, Tara Street and Pearse Street. The train also serves stations along the Maynooth/Longford line. Clonsilla connects to the Dublin–Navan railway line as far as the Pace M3 "Park and Ride" which also stops at Hansfield and Dunboyne.
Ballycoolin Industrial Estate is served by a private bus company called AMC Ballycoolin, also known as Express Bus.
Dublin Bus routes include 17A, 37, 38, 38A, 38B, 39, 39A, 40D, 70, 76A, 220, 236, 238, 239 and 270.
