Ruxley (previously Rokesley, and in the Domesday Book Helmestrei) was an ancient hundred, a land division in the north west of the county of Kent, England. Its area has been mostly absorbed by the growth of London; with its name currently referring to the Ruxley district. Its former area now corresponds to a majority of the London Borough of Bromley, a large part of the London Borough of Bexley and a small part of the Kent District of Sevenoaks. The hundred was within the Lathe of Sutton-at-Hone, in the west division of Kent.
