Castletown House, Celbridge, County Kildare, Ireland, is a Palladian country house built in 1722 for William Conolly, the Speaker of the Irish House of Commons. It formed the centrepiece of an 800-acre (320 ha) estate. The estate was sold in 1965, and later sub-divided.
The house and a core demesne of 120 acres were bought by a group of people looking to preserve them, and became the first major project of the Irish Georgian Society; they were later transferred to a dedicated charitable foundation, and ultimately to State ownership. Most of the wider estate remaining was divided between State forestry company, Coillte, and developers, and parts were built on, notably the former orchard and walled garden. In September 2023, the main access road and car parking became the subject of access issues and protests. In November 2025 it was announced the State, through the Office of Public Works had successfully concluded a sale agreement with the private owner of the remaining part of the Castletown Demesne, enabling resolution of these issues.
