Belmayne is a development of housing, and adjunct facilities, in Balgriffin, a northern suburb of Dublin, Ireland, commenced in 2006/7.
Belmayne is situated in the angle of the Malahide Road and the N32, opposite the Hilton Hotel in Belcamp. It is close to the M1 and M50, motorways and Dublin Airport, via the N32. There are Dublin Bus services (27, 42, 43 and 128) on the Malahide Road, and Clongriffin DART station is 15-20 minutes walk away.
Belmayne forms part of the Northern Fringe Development, as approved by the local authorities, providing new accommodation in former "green belt" land.
Adjacent housing developments in Balgriffin include Castlemoyne and St. Samson's Court, both to the north.
While there are very limited retail and civic amenities inside, the estate is in walking distance of Tesco-anchored Clare Hall Shopping Centre and the Northern Cross shopping area which includes a EuroSpar supermarket and a restaurant.
There are two primary schools (St. Francis of Assisi Catholic school and Educate Together multi-denominational school) and a creche (Bumblebees) within the estate.
In addition, the estate is served by Belmayne Mass Centre, as well as the parish church located in Donaghmede, for Roman Catholics, and by St. Doulagh's Church in northern Balgriffin, for Church of Ireland adherents.
The development was begun by Stanley Holdings in 2006, with construction by LM Developments. Originally a civic centre was promised, agreed between City Council and developers, on a specified block of lands. Facilities, including a library, were included, but this proposal was later repudiated by the developers on economic grounds, and the lands transferred from the City Council to a special government agency.
Belmayne was later the subject of urgent fire safety works, but without the evacuation of residents experienced in nearby Priory Hall, Donaghmede.
Parts of the development remain incomplete.
Belmayne has been noted in the press and criticised by some members of the public for its striking advertising theme material. It was later found that the developers were non-compliant with Advertising Standards
The Turnapin Stream branch of the River Mayne flows through part of the development, just north of the main line, meeting the other main branch a little to the east.
