Blanchardstown (Irish: Baile Bhlainséir)[1] is a large outer suburb of Dublin in the modern county of Fingal, Ireland.

Located ten kilometres (6 mi) northwest of Dublin city centre, it has developed since the 1960s from a small village to a point where Greater Blanchardstown is the largest urban area in Fingal.

One of Ireland's largest shopping and leisure complexes — the Blanchardstown Centre and adjacent facilities — is located in the area.

[2] Blanchardstown is just outside Dublin's M50 motorway semi-ring road, slightly to the north of the tolled crossing of the River Liffey.

The stretch of suburban housing from Castleknock Way north to the Old Navan Road and Talbot Court, including Laurel Lodge, has an ambiguous status - all of it is in the townland of Blanchardstown.

The Royal Canal and the Dublin-Sligo railway line pass along the southern edge of Blanchardstown proper from east to west.

Blanchardstown was a predominantly rural area, with a small village, in western County Dublin, alongside the neighbouring district of Castleknock.

[14] Express bus routes include service from Aston Quay and from Coolmine Railway Station to Ballycoolin Industrial Estate.

[citation needed] There are several GAA clubs in the Blanchardstown area, including St. Brigids, Castleknock and St. Peregrines, Clonsilla.

Following the relaxation of the Penal Laws, it became possible for Catholic adherents to consider the construction of additional churches and to repair the existing stock of religious buildings.

[28] For the purposes of elections to Dáil Éireann, Blanchardstown is part of the Dublin West constituency, which returns four TDs.
