Jedh Colby Barker (June 20, 1945 – September 21, 1967) was a United States Marine Corps Lance Corporal who posthumously received the Medal of Honor for heroism during the Vietnam War in September 1967. While participating in Operation Kingfisher, Barker's platoon was attacked by North Vietnamese forces in the western part of the Leatherneck Square. The platoon got into cover, and Barker lay down suppressing fire on the Vietnamese positions. When a grenade was thrown into the American defensive position, Barker jumped onto it and saved the lives of fellow injured Marines.
