Collinstown (from Irish Baile Choilín[1]) is a townland in Fingal, County Dublin, roughly 7 km north of Dublin in Ireland.
This area is in the civil parish of Santry, within the barony of Coolock.
[1] The townland is entirely within the perimeter of Dublin Airport, which grew out of Collinstown Aerodrome, originally a Royal Air Force station.
[2][3][4] Construction of the airport followed, and it expanded over time, spreading into neighbouring administrative areas.
