Liscarroll Castle is a 13th-century Hiberno-Norman fortress in County Cork, Ireland. In July 1642, at the start of the Irish Confederate Wars, the castle was seized by Irish Confederate forces commanded by Garret Barry. After the subsequent Battle of Liscarroll, the castle was recaptured by British forces commanded by Murrough O'Brien, 1st Earl of Inchiquin. The castle is the subject of an 1854 poem by Callaghan Hartstonge Gayner which concludes: The remains of Castle Liscarroll still tower over the village of Liscarroll and the surrounding countryside.
