The Ford 999 was a nameplate attached to two distinct but similar racers built by Henry Ford during the early 20th century. Though they began as separate entities, they were virtually mechanically identical, and parts were swapped between them as needed, making the identities and legacies inseparable.

Henry Ford was an American industrialist and business magnate. As the founder of the Ford Motor Company he is credited as a pioneer in making automobiles affordable for middle-class Americans through the system that came to be known as Fordism. In 1911 he was awarded a patent for the transmission mechanism that would be used in the Model T and other automobiles.
