Korat Royal Thai Air Force Base is a base of the Royal Thai Air Force (RTAF) in northeast Thailand, approximately 200 km (125 mi) northeast of Bangkok and about 4 km (2.5 mi) south of the centre of the city of Nakhon Ratchasima in the Nakhon Ratchasima Province (also known as "Khorat" or "Korat"), the largest province in Thailand.

During the Vietnam War, from 1962 to 1975, Korat RTAFB was a front-line facility of the United States Air Force (USAF) in Thailand.

During the 1980s and early-1990s, the airfield was jointly operated as a civil airport for Nakhon Ratchasima. This ended with the opening of Nakhon Ratchasima Airport in the early-1990s.
