The Belgian Sport Horse, Dutch: Belgisch Sportpaard, French: Cheval de Sport Belge, is a Belgian breed of warmblood sport horse.

It is bred for dressage, for show-jumping and for three-day eventing.

[4]: 164 The Belgian Sport Horse has its origins in the early twentieth century, when warmblood horses were bred by cross-breeding imported Selle Français and Thoroughbred stallions with local animals of the Belgian Draught breed, with the intention of producing cavalry horses.

[3]: 444  Later influences were from Selle Français, Dutch Warmblood and Hanoverian.

A breed society, La Société d'Encouragement pour l'Elevage du Cheval d'Armes, was established in 1920;[5] from about 1930 the principal aim was to breed horses for leisure use[3]: 444  and the name Société du Cheval de Demi-sang Belge was adopted.
