Castlehyde (Irish: Carraig an Éidigh)[1] is a townland and estate, slightly west of Fermoy in County Cork, Ireland.

[3] The townland of Castlehyde, which is c. 32 hectares (79 acres) in area,[4] is in the civil parish of Fermoy and the historical barony of Condons and Clangibbon.

[15] At the time of the sale in 1851, Castlehyde House was occupied by Spencer Cosby Price, the brother-in-law of John Hyde.

[16] The house passed through several owners, including members of the Wrixon-Becher family,[10] and by the 1940s the building was reputedly "occupied by the military".

[3] As of mid-2020, Flatley was reputedly seeking to sell the property,[2] but subsequently decided against the sale stating that he was "too emotionally attached to Castlehyde".
