Earl Sondes, of Lees Court in the County of Kent, was a title in the Peerage of the United Kingdom. It was created in 1880 for the former Conservative Member of Parliament for East Kent, George Milles, 5th Baron Sondes. He was made Viscount Throwley, of the County of Kent, at the same time, which title was used as a courtesy title by the eldest son and heir apparent of the Earl. The titles became extinct on the death of his great-grandson, the fifth Earl, in 1996.
