First Sergeant Rudolph Stauffer (November 27, 1836 – June 9, 1918) was a Swiss-born American soldier in the U.S. Army who served with the 5th U.S. Cavalry in the Apache Wars. He was one of twelve soldiers, along with ten Apache Scouts, awarded the Medal of Honor during Lieutenant Colonel George Crook's "winter campaign" of 1872–73, being cited for gallantry in battle against renegade Apaches near Camp Hualpai. Charles King, while serving with the 5th U.S. Cavalry in his youth, wrote of him in his memoirs as "grim old Stauffer, the first sergeant".
