Adamstown is a planned suburban development in western County Dublin, Ireland located circa 16 km from Dublin city centre in the jurisdiction of South Dublin County Council. The first new town in Ireland since Shannon Town in the 1960s, the development-in-progress is based on a 220 hectare Strategic Development Zone site south of the N4 road and Lucan, west of a River Liffey tributary, the Griffeen River, and north of the Grand Canal.
