Tyrrelstown (Irish: Baile an Tirialaigh) is a townland in the civil parish of Mulhuddart, located 13 km northwest of the city of Dublin in Ireland and often considered as part of the greater Blanchardstown area. It is the site of a planned suburban development from the early 2000s. The local authority for the area, which forms part of the Dublin 15 postal district, is Fingal County Council.
Tyrrelstown (often also spelt as Tyrellstown or Tyrrellstown) derives its name from that of the Tyrrell family, which was granted the lands in the parishes of Clonsilla and Mulhuddart in 1178 by Hugh de Lacy, Lord of Meath. Historically Tyrrelstown is part of the barony of Castleknock, which had its focal point at Castleknock Castle; much of the area's history is intertwined with that of Cruiserath, Castleknock, Mulhuddart and other adjacent places. To the south there is Tyrrelstown House, a protected structure dating back to 1720. About 1580 Tyrrelstown was granted to the Bellings family, whose most prominent member was Richard Bellings, one of the leaders of Confederate Ireland.
Located nearby is Damastown Industrial Estate, one of Dublin's largest industrial estates, which includes a major IBM campus, employing over 4,000 people. In Cruiserath, also nearby, there are premises for the pharmaceutical corporation Bristol-Myers Squibb, while beyond is Blanchardstown Corporate Park which features offices belonging to PayPal, Ask.Com, and Welocalize, a multinational software localization company.
Local amenities include two national schools (one under the patronage of Educate Together and a second that of the Catholic Church), a central retail facility, Tyrrelstown Town Centre (2005), a hotel (2006), a creche, Lidl and SuperValu supermarkets, and various other retailers and food and drink premises.
There is also a GAA club, Tyrrelstown GAA, playing football and hurling up to Under 12 and also fielding an adult junior football team in AFL Division 10 North County.
Tyrrelstown is served primarily by the regular 40D Dublin Bus route from Dublin City Centre. In addition a 238 service links the area with Blanchardstown Shopping Centre and Ladyswell.
A new N2 - N3 link road was completed in May 2013 and passes by Tyrrelstown, improving the development linkages to the M2 (Dublin-north east motorway). By road it is accessible via Mulhuddart, Hollystown and Cruiserath.
The main modern Tyrrelstown residential development was driven by Dublin property company Twinlite, and launched in 2001. Other development companies involved include McInerney Construction, Kranok Construction and Merville Homes. Originally the site was zoned for a landfill that was scrapped; the settlement now hosts over 5,500 inhabitants. The architects for the main development were J. F. O'Connor of Harolds Cross.
