The title of Baron Bonville was created once in the Peerage of England. On 10 March 1449, Sir William Bonville II was summoned to Parliament. On his death in 1461, the barony was inherited by his great-granddaughter Cecily Bonville, who two months before succeeded as Baroness Harington, with which title the barony merged until 1554, when both baronies were forfeited. From her death in 1529 to the forfeiture in 1554, the baronies were merged with the title of Marquess of Dorset.
