The 4727th Air Defense Group is a discontinued United States Air Force organization. Its last assignment was with the Syracuse Air Defense Sector at Griffiss Air Force Base, New York, where it was discontinued in 1959.

The group was formed to provide a single command and support organization for the two fighter interceptor squadrons of Air Defense Command (ADC), that were tenants at Griffiss, an Air Materiel Command (AMC) base. It was also assigned a maintenance squadron to perform aircraft maintenance. It was discontinued after the 27th Fighter-Interceptor Squadron moved in 1959, leaving only a single fighter squadron at Griffiss.

The group was established to provide a headquarters for Air Defense Command (ADC) Fighter-Interceptor Squadrons (FIS) stationed at Griffiss Air Force Base, an Air Materiel Command base, whose Rome Air Force Depot (until February 1958) and 2856th Air Base Wing (after February 1958) acted as host base organizations for the group. The 4727th was assigned the 27th Fighter-Interceptor Squadron (FIS), flying Lockheed F-94 Starfire aircraft and 465th FIS, flying Northrop F-89 Scorpions as its operational components. The interceptor aircraft assigned to these squadrons were armed with Mighty Mouse rockets. The F-89s were also armed with Falcon missiles or Genie rockets. All assigned aircraft were equipped with data link for interception control through the Semi-Automatic Ground Environment system
