Arthur Jules Joseph Duray was a Belgian racing driver and aviator. He was one of the first Belgians to pilot an aircraft, holding Belgian license #3. Duray is best known for breaking the land speed record on three separate occasions between July, 1903 and March, 1904.

The land speed record (LSR) or absolute land speed record is the highest speed achieved by a person using a vehicle on land. By a 1964 agreement between the Fédération Internationale de l'Automobile (FIA) and Fédération Internationale de Motocyclisme (FIM), respective governing bodies for racing in automobiles and motorcycles, both bodies recognise as the absolute LSR whatever is the highest speed record achieved across any of their various categories. While the three-wheeled Spirit of America set an FIM-validated LSR in 1963, all subsequent LSRs are by vehicles in FIA Category C in either class JE or class RT.
