The 624th Regional Support Group, headquartered at Hickam Air Force Base, Hawaii, is one of two Air Force Reserve groups stationed in the Pacific Area of Responsibility and reports directly to the headquarters of the Fourth Air Force at March Air Reserve Base, California.

The group is composed of a headquarters, four squadrons, and one flight at Hickam Air Force Base, Hawaii, and Andersen Air Force Base, Guam.

The 624th Regional Support Group was established on 1 January 2002, resulting from the reorganization of resources from various entities. The group emerged from the transformation of the 604th Regional Support Group, with personnel and components from several sources. The formation involved changes to existing units and designations. For instance, the 604th Aeromedical Staging Squadron, the 604th Logistics Support Flight, and the 704th Civil Engineer Squadron at Hickam, were respectively replaced by the 624th Aeromedical Staging Squadron, 624th Logistics Support Flight (subsequently inactivated), and 624th Civil Engineer Squadron. Moreover, the 604th Aeromedical Staging Squadron operating location at Andersen was replaced by the 724th Aeromedical Staging Flight and 724th Logistics Support Flight (which is no longer active). The 48th Aerial Port Squadron at Hickam and the 44th Aerial Port Squadron at Andersen were transferred to the 624th Group.
