Ballyroan (Irish: Baile Uí Ruáin, meaning "O'Rowan's town")[1] is a suburb in Rathfarnham, County Dublin in Ireland. It lies at the foot of the Dublin mountains, alongside Ballyboden, Butterfield, Knocklyon, Old Orchard, and Scholarstown. The townland of Ballyroan crosses civil parish and barony boundaries with roughly 114 acres of the historical townland in the civil parish of Tallaght in the barony of Uppercross, and nearly 10 acres in the civil parish of Rathfarnham in the barony of Rathdown.[2] The modern suburb of Ballyroan has extended somewhat beyond the traditional townland boundaries.[3]
The centre of Ballyroan contains the Rosemount shopping centre, the Ballyroan public library which opened in 1986,[4] and the parish church which opened in December 1967. The interior walls of the church contain two murals by the artist, Seán Keating.[5] There are two secondary schools, Sancta Maria College and Coláiste Éanna, and a local scout troop.[6]
Ballyroan is served by the 15B bus route.[7]
The international golf player Pádraig Harrington is from the area.
