John Denny (c. 1846 – November 26, 1901) was a Buffalo Soldier in the United States Army and a recipient of America's highest military decoration—the Medal of Honor—for his actions in the Indian Wars of the western United States.

Denny joined the Army from Elmira, New York in 1869, and, by September 18, 1879, was serving as a First Sergeant in Company C of the 9th Cavalry Regiment. On that day, his unit participated in an engagement against Chief Victorio and his band of Apaches at Las Animas Canyon, New Mexico, and Denny "[r]emoved a wounded comrade, under a heavy fire, to a place of safety." For his actions, Sergeant Denny was awarded the Medal of Honor fifteen years later, in January 1895.

Denny retired from the Army in September 1897 as a corporal. He received a pension but also worked at the Fort Robinson post exchange. He moved to the US Soldiers' Home in Washington, D.C. sometime in or after 1899 and died there in 1901.^[1] Denny was buried at the United States Soldiers' and Airmen's Home National Cemetery in Washington, D.C.
