Viscount Scarsdale and Baron Scarsdale are titles in the Peerage of the United Kingdom and Peerage of Great Britain, respectively. The Barony was created in 1761 for Sir Nathaniel Curzon, 6th Baronet, of Kedleston. The Viscountcy was created in 1911, along with the titles of Earl Curzon of Kedleston and Baron Ravensdale for George Nathaniel Curzon, eldest son of the fourth Baron Scarsdale, who had been created Baron Curzon of Kedleston in the Peerage of Ireland in 1898 and elected an Irish Representative Peer in 1908. Lord Curzon of Kedleston succeeded his father as 5th Baron Scarsdale in 1916, and was further created Marquess Curzon of Kedleston in 1921. The Curzon of Kedleston titles became extinct at his death, but the Barony of Scarsdale and (thanks to a special remainder) the Viscountcy passed to his nephew, who became 6th Baron and 2nd Viscount Scarsdale. The Barony of Ravensdale passed under a different remainder to his daughter, Mary Irene .
