county in the province of Leinster, east-central Ireland. It comprises part of the lowland west of the Wicklow Mountains and part of the Irish central lowland. County Kildare is bounded by Counties Meath (north), Dublin and Wicklow (east), Carlow (south), and Laoighis and Offaly (west). The River Liffey forms a gorge at Pollaphuca and runs west into the Kildare lowland, northwest to Newbridge, and northeast to Celbridge and Leixlip. The River Barrow forms much of the county's western boundary. Glacial deposits cover much of the surface of Kildare, and soils are varied; more than four-fifths of the area is farmland.
