Baron Carew is a title that has been created three times. The first creation was in the Peerage of England in 1605. The first recipient, Sir George Carew (1555–1629), was later made Earl of Totnes in 1626. Both titles became extinct on his death as he left no heirs. Between 1956 and 1965 the sixth Baron was the owner of Castletown House and Estate in County Kildare, regarded as one of Ireland's finest country houses and now a museum open to the public and in the ownership of the Irish State.
