Baron Berkeley of Stratton, in the County of Cornwall, was a title in the Peerage of England. It was created in 1658 for John Berkeley, 1st Baron Berkeley of Stratton, a Royalist supporter during the English Civil War, of the Bruton branch of the Berkeley family. He was a descendant of Sir Maurice de Berkeley (14th century), younger son of Maurice de Berkeley, 2nd Baron Berkeley (see Baron Berkeley). Charles Berkeley, 2nd Viscount Fitzhardinge, was his brother and Charles Berkeley, 1st Earl of Falmouth, his nephew. Lord Berkeley of Stratton's second son, the third Baron (who succeeded his elder brother), was an Admiral in the Royal Navy. He died without surviving children and was succeeded by his younger brother, the fourth Baron. He was a politician and served as First Lord of Trade between 1714 and 1715. On his death the title passed to his eldest son, the fifth Baron. He was also a politician and held office as Captain of the Yeomen of the Guard and Captain of the Honourable Corps of Gentlemen-Pensioners. He was childless and the title became extinct on his death in 1775.
