Belgian Count Henri de Baillet-Latour (March 1, 1876-January 6, 1942) was the third president of the International Olympic Committee (IOC).

De Baillet-Latour became a member of the IOC in 1903, later also co-founding the Belgian Olympic Committee. He was one of the organisers of the 1920 Summer Olympics in Antwerp, which were awarded only in 1919. Despite the short preparation time and the state Belgium was in after the First World War, the Games were a success.

When the founder of the modern Olympic Movement, Pierre de Coubertin, resigned as the IOC president in 1925, De Baillet-Latour was elected president. He lead the IOC until his death in 1942, when he was succeeded by vice-president Sigfrid Edström.
