McEntire Joint National Guard Base or McEntire JNGB (IATA: MMT, ICAO: KMMT, FAA LID: MMT) is a military airport located in Richland County, South Carolina, United States, 10 miles (16 km) west of the town of Eastover and approximately 15 miles southeast of the city of Columbia.

McEntire died on 25 May 1961 when he rode his malfunctioning F-104 Starfighter into the Susquehanna River to avoid crashing in the populated area of Harrisburg, Pennsylvania.

The 406th Bombardment Group (Dive) replaced it, arriving on 18 September 1943 and remaining until being deployed to Ninth Air Force in England on 18 March 1944.

On 31 March 1944, Congree was removed from the jurisdiction of Columbia AAB, and on 30 April Congaree AAF was transferred to the United States Navy.

One of the fields major problems was a lack of bombing and gunnery ranges, which meant regular deployments to Marine Corps Air Station Parris Island for training.

By November 1945, all Marine aviation units had moved to MCAS Cherry Point, North Carolina.

The South Carolina Air National Guard also has a state mission, to respond to the call of the governor in the event of natural disaster or domestic disturbance.

The 59th Aviation Troop Command of the South Carolina Army National Guard (SCARNG) is also located at McEntire JNGB.
