Eugène-Henri Gravelotte (6 February 1876 in Paris – 23 August 1939) was a French fencer. He was the first modern Olympic champion in foil, winning the event at the 1896 Summer Olympics in Athens.
Gravelotte was undefeated in his group for the preliminary round, defeating Greek fencers Athanasios Vouros, Konstantinos Komninos-Miliotis, and Georgios Balakakis in succession. He then faced fellow Frenchman Henri Callot, who had gone undefeated in the other group, in the final. Gravelotte won that match 3-2.
