Killeen Castle (Irish: Caisleán Chillín), located in Dunsany, County Meath, Ireland, is the current construction on a site occupied by a castle since around 1180. The current building is a restoration of a largely 19th century construction, burnt out in 1981. Killeen was built as one of a pair of castles either side of a major roadway north, the other being the extant Dunsany Castle.
