Cleone Benest (13 June 1880 – 23 December 1963), also known by the pseudonym C. Griff, was a pioneering motorist, as well as an engineer, and metallurgist. She was one of the first women engineers to pass mechanical examinations of the City and Guilds of London Institute, Royal Automobile Club, and Portsmouth Municipal College.
