Active duty United States four-star officers
There are currently 44 active-duty four-star officers in the uniformed services of the United States: 15 in the Army, three in the Marine Corps, eight in the Navy, 12 in the Air Force, three in the Space Force, two in the Coast Guard, and one in the Public Health Service Commissioned Corps. Of the eight federal uniformed services, the NOAA Commissioned Officer Corps is the only service that does not have an established four-star position.

Modern day four-star officers' ranks are usually referred to as full general or full admiral, the officers themselves being referred to and addressed as 'General' or 'Admiral'. Four-star officers are ranked in seniority by their time-in-grade and/or by statute via the position of office they hold.
