The Marmon-Herrington Armoured Car was a series of armoured vehicles that were produced in South Africa and adopted by the British Army during the Second World War. RAF Armoured Car companies possessed them, but seem never to have used them in action, making greater use of Rolls-Royce Armoured Cars and other types.

The Marmon-Herrington Company, Inc. is an American manufacturer of axles and transfer cases for trucks and other vehicles. Earlier, the company built military vehicles and some tanks during World War II, and until the late 1950s or early 1960s was a manufacturer of trucks and trolley buses. Marmon-Herrington had a partnership with Ford Motor Company, producing trucks and other commercial vehicles, such as buses. The company may be best known for its all-wheel-drive conversions to other truck maker's units, especially to Ford truck models. Founded in 1931, Marmon-Herrington was based in Indianapolis, Indiana, with a plant in Windsor, Ontario, and remained in Indianapolis until 1963. It is now based in Louisville, Kentucky.
