The Harmon Trophy is a set of three international trophies, to be awarded annually to the world's outstanding aviator, aviatrix, and aeronaut. A fourth trophy, the "National Trophy," was awarded from 1926 through 1938 to the most outstanding aviator in each of the twenty-one member countries and again from 1946–1948 to honor Americans who contributed to aviation. The award was established in 1926 by Clifford B. Harmon, a wealthy balloonist and aviator.

Gervais Raoul Victor Lufbery was a French and American fighter pilot and flying ace in World War I. Because he served in both the French Air Force, and later the United States Army Air Service in World War I, he is sometimes listed alternately as a French ace or as an American ace. Officially, all but one of his 17 combat victories came while flying in French units.
