Shaw Air Force Base (Shaw AFB) (IATA: SSC, ICAO: KSSC, FAA LID: SSC) is a United States Air Force (USAF) base located approximately 8.4 miles (13.5 km) west-northwest of downtown Sumter, South Carolina. It is one of the largest military bases operated by the United States, and is under the jurisdiction of USAF Air Combat Command (ACC). The 20th Fighter Wing (20th FW) is the host unit.

The base is named in honor of World War I pilot 1st Lieutenant Ervin David Shaw. Lt. Shaw was one of the first Americans to fly combat missions in World War I. Shaw, a Sumter County native, was assigned to No. 48 Squadron of the Royal Air Force, as a member of the Royal Canadian Flying Corps. Shaw died after three enemy aircraft attacked his Bristol F.2B while he was returning from a reconnaissance mission on 9 July 1918. Shaw downed one of his attackers before he was killed.

Shaw Field was activated on 30 August 1941 and placed under the jurisdiction of the U.S. Army Air Corps Southeast Air Corps Training Center. The mission of the new airfield was a basic (Phase II) flying school to instruct air cadets in flying, and the Air Corps Basic Flying School was activated at the field on 26 June to operate the school. The airfield consisted of three 4,500-foot (1,400 m) runways and several auxiliary airfields.

Flying activities at the field began on 22 October 1941 using Vultee BT-13 Valiants. Enough construction was completed for the first group of cadets entered training 15 December 1941, and the first class completed training in February 1942. The concrete parking ramp was completed during May 1942.

In October 1942, the flight training was changed to Advanced (Phase III) flying training and AT-6 Texan single-engine and Beech AT-10 twin-engine trainers were used. During World War II, the U.S. Army Air Forces (USAAF) Pilot School, under the USAAF Southeast Training Center trained more than 8,600 pilots in the basic and advanced flying curriculum, its graduates were then sent to Advanced Flight Training in single or multi-engine aircraft.

On 1 April 1945 jurisdiction of Shaw Field was transferred to the First Air Force. The 139th Army Air Force Base Unit, I Fighter Command became the host unit. and pilots were sent to Shaw for fighter transition training in Republic P-47 Thunderbolt single-engined fighters.

For a brief time, Shaw Field also served as a prisoner-of-war (POW) camp. The first group of German POWs arrived on 1 March 1945. Eventually, 175 of them lived in an encampment just off the main base, on Peach Orchard Road (also known as South Carolina Highway 441) across from Shaw's (side) hospital (currently closed) gate and worked on local farms in the area. They departed in the early months of 1946 for the rebuilding of European cities and towns that were devastated during the war. Those prisoners were eventually repatriated to Germany around 1947, with some returning to the Shaw and Sumter area and obtaining their U.S. citizenship.

Shaw Army Airfield was designated a permanent USAAF installation after the war, being transferred to Continental Air Forces on 16 April 1945. After a period of reorganization, jurisdiction was transferred to Air Defense Command on 1 March 1946. From July 1946 until May 1947 Shaw was the home of the 414th and 415th Night Fighter Squadrons.
