The 24 Hours of Spa is an endurance racing event for cars held annually since 1924 at the Circuit de Spa-Francorchamps, Stavelot, Belgium.

It debuted in 1924 over a 15 kilometres (9.3 mi) circuit on public roads between the towns of Francorchamps, Malmedy and Stavelot, under the auspices of the Royal Automobile Club of Belgium (RACB).

Cars entered have spanned from the Russian Moskvitch and models with sub-1 liter engines such as the NSU Prinz TT to the luxurious V8-powered Mercedes-Benz 300 SEL 6.3.

During the 1975 race, Dutch driver Wim Boshuis and a track marshal were killed in two separate incidents.
