The 568th Air Defense Group is a disbanded United States Air Force organization. Its last assignment was with Air Defense Command (ADC)'s 4709th Air Defense Wing at McGuire Air Force Base, New Jersey, where it was inactivated in 1954. The group was originally activated as the 568th Air Service Group, a support unit for a combat group at the end of World War II on Guam, but was soon inactivated.

The group was activated once again in 1952 at McGuire Air Force Base, New Jersey as the 568th Air Base Group to replace the support elements of the inactivating 52d Fighter-Interceptor Wing. A year later Air Defense Command ADC established it as an operational headquarters for fighter-interceptor squadrons as well. It was replaced in 1954 when ADC transferred host fundctions at McGuire to Military Air Transport Service and its operational squadrons were transferred to other ADC units.
