The 518th Air Defense Group is a disbanded United States Air Force organization. Its last assignment was with the 4707th Air Defense Wing, stationed at Niagara Falls Municipal Airport, New York, where it was inactivated in 1955.

The group was originally activated the 518th Air Service Group, a support unit for the 465th Bombardment Group at the end of World War II in Italy and then redeployed to the Caribbean, where it supported redeploying units until it was inactivated in 1945.

The group was activated once again in 1953, when Air Defense Command (ADC) established it as the headquarters for a dispersed fighter-interceptor squadron and the medical, aircraft maintenance, and administrative squadrons supporting it. It was replaced in 1955 when ADC transferred its mission, equipment, and personnel to the 15th Fighter Group in a project that replaced air defense groups commanding fighter squadrons with fighter groups with distinguished records during World War II.
