Eugenio Brunetta d'Usseaux (14 December 1857 – 8 January 1919) was an Italian nobleman and member of the International Olympic Committee.

[1] His father, the count Carlo Augusto Brunetta of Usseaux was a high-ranking official of the Royal Sardinian Army, headquartered in the same city.

His engagement for the sports (ideals) was so very close to him, that in 1897 Brunetta d'Usseaux become member of the International Olympic Committee (IOC), which he remained until his death, as general secretary since 1908.

This was opposed by the Swedish organizers, but Brunetta d'Usseaux managed to get a winter sports week scheduled for 1916.

The count died, under unclear circumstances,[4] in France in 1919, and would not live to see the first Winter Olympic Games in 1924, maybe in Nice.
