Powhatan Henry Clarke (October 9, 1862 – July 21, 1893) was a United States Army first lieutenant who was a recipient of the Medal of Honor during the Geronimo Campaign in Sonora, Mexico.

[4][5] On May 3, 1886, he rescued one of his wounded soldiers, Corporal Edward Scott, who was under heavy fire from Apaches at Pinito Mountains, Sonora.

That same year, he became a compatriot of the District of Columbia Society of the Sons of the American Revolution and was assigned national membership number 1976.

After diving into shallow water and striking his head, Clarke drowned in the Little Bighorn River on July 21, 1893,[7] and was buried at Calvary Cemetery in St. Louis, Missouri.
