This is a list of Groups in the United States Air Force that do not belong to a host wing.

The last level of independent operation is the group level. When an organization is not part of the primary mission of the base it will be made an independent group. They may report to a wing or they may be completely independent (the 317th Airlift Group at Dyess Air Force Base). They may also be organized as an expeditionary unit, independent but too small to warrant a wing designation. The organization of the independent group is usually similar to the operations group, but with a few squadrons or flight from the support side added to make the organization more self-sufficient, but not large enough to become a wing.

The 1st, 2nd, and 9th Aeromedical Evacuation Groups all previously existed.

The 427th Special Operations Training Squadron (tail code IJ) at England Air Force Base, Louisiana, flew the Cessna A-37 Dragonfly (OA-37B FAC variant) from 1970–1972, assigned to the provisional 4410th Special Operations Training Group, Tactical Air Command.

During and immediately after the Korean War, Tactical Air Command (TAC) trained aircrews for the Douglas B-26 Invader at Langley Air Force Base, Virginia. The three squadrons of the 4400th Combat Crew Training Group performing this mission were Air National Guard units that had been mobilized for the war. At the start of 1953, these squadrons were returned to state control and the 423d Bombardment Squadron was activated^[1] and took over the mission, personnel, and equipment of the 117th Bombardment Squadron, which returned to the Pennsylvania Air National Guard.^[2] In January 1954, the group mission shifted to tactical bombardment and it was redesignated the 4400th Bombardment Group. The group expected to transition to Martin B-57 Canberra aircraft. As this was to take place, TAC decided to replace the Table of Distribution 4400th Group and its squadrons with the regular 345th Bombardment Group, which took over their mission in July 1954^[3] and the 423d BS was inactivated.^[1]

In 1988, Tactical Air Command activated the 4443rd Test and Evaluation Group as an operational test unit at Eglin Air Force Base, an Air Force Systems Command (AFSC) base.

The 4450th Standardization Evaluation Group (SEG) was activated in the early 1960s.

Colonel Abner M. Aust served as Deputy Commander and then Commander of the 6002nd Standardization Evaluation Group at Kadena Air Base, Okinawa, from September 1963 to June 1965.^[4] The group was inactivated on 20 November 1967.

It appears that the 6903rd, 6912th, 6917th, and 6920th Electronic Security Groups all previously existed. The 6922d Security Group was activated in April 1970 at Clark Air Base in the Philippines.^[5] Initially, the group intercepted and listened to foreign electronic communications through subordinate detachments ranging from Thailand through Japan. With the withdrawal of the United States from Vietnam, operations were substantially reduced, and by 1974 were limited to direction finding, and the group was reduced to the 6922d Security Squadron.

After the departure of its last flying squadron, the 25th Tactical Reconnaissance Wing wing continued to wind down operations at Chambley Air Base, France, until 15 October 1966, when it inactivated, although it was no longer operational.^[6] Its remaining support personnel were transferred to the 7367th Tactical Group, which managed US Air Force operations at Chambley until they terminated in April 1967.^[7][8]

The 7382nd Guided Missile Group (Tactical) was stationed at Hahn Air Base, West Germany, in the 1960s, before being replaced by the 701st Tactical Missile Wing.
