The barony of Castleknock is one of the baronies of Ireland. Originally part of the Lordship of Meath, it was then constituted as part of County Dublin. Today, it is in the modern county of Fingal, Ireland. The barony was originally also a feudal title, which became one of the subsidiary titles of the Viscounts Gormanston.
