Marine Aircraft Group 43 (MAG-43) was a fixed wing aviation group in the United States Marine Corps Reserve based at Naval Air Station Joint Reserve Base Willow Grove, Pennsylvania.
The group was originally formed during World War II as the administrative headquarters for all Marine Corps units training at Marine Corps Air Station El Centro, California. A mission change in late 1944 saw MAG-43 tasked to serve as the headquarters for the Air Defense Command of the Tactical Air Force, Tenth Army during the Battle of Okinawa. In this role the group was responsible for the employment of all land based fighters, radars and antiaircraft units. The group was later re-designated as Marine Air Control Group 2 (MACG-2) and saw service during the Korean War again overseeing Marine Corps aviation command and control equities. Deactivated in July 1955, the group was reactivated in 1962 as a part of a restructure of aviation within the Marine Corps Reserve. In 1969 the group was transferred to the 4th Marine Aircraft Wing until its deactivation in September 1972.
