Baron Dunalley, of Kilboy in the County of Tipperary, is a title in the Peerage of Ireland. It was created in 1800 for Henry Prittie, who had previously represented Banagher, Gowran and County Tipperary in the Irish House of Commons. His son, the second Baron, represented Carlow in the Irish Parliament and Okehampton in the British House of Commons and also sat in the House of Lords as an Irish Representative Peer from 1828 to 1854. He was succeeded by his nephew, the third Baron. When he died the barony was inherited by his son, the fourth Baron. He was an Irish Representative Peer between 1891 and 1927 and served as Lord Lieutenant of County Tipperary. As of 2014 the title is held by his great-grandson, the seventh Baron, who succeeded his father in 1992.
The family house was Kilboy House, near Nenagh, County Tipperary which was built in 1771 to the design of William Leeson Architect. The house was torched by the IRA on 8 August 1922. A compensation claim was made to the new Irish Government, but the payment which they made was not sufficient to return the house to its former glory.
