James Jackson (November 21, 1833 – October 21, 1916) was an American officer in the U.S. Army during the mid-to late 19th century. He was a captain with the 12th Iowa Volunteer Infantry Regiment during the American Civil War and with the 1st U.S. Cavalry in the Indian Wars. While fighting the Nez Percé at Battle of Camas Meadows in 1877, he risked his life to recover the body of another soldier preventing its mutilation by the enemy. For this act, he received the Medal of Honor nearly 20 years later.
