Warbird is any vintage military aircraft now operated by civilian organisations and individuals or, in some instances, by historic arms of military forces, such as the Battle of Britain Memorial Flight, the RAAF Museum Historic Flight and the South African Air Force Museum Historic Flight.
Restored warbirds are a frequent attraction at airshows. Highly modified as well as "stock" warbirds can also frequently be seen at air races, since World War II-era fighters are among the fastest propeller-driven airplanes ever built. Some of the most popular warbirds for races are the North American P-51 Mustang, the Hawker Sea Fury, the Grumman F8F Bearcat and the North American T-6 Texan.
Although the term originally implied piston-driven aircraft from the World War II era, it is now often extended to include all airworthy former military aircraft, including jet-powered aircraft. Vintage jet aircraft in airworthy condition, however, are much rarer due to technical complexity.
Sometimes, newly built replicas and reproductions of vintage aircraft are called "warbirds," such as Allison V-1710-powered Yakovlev Yak-9s from Yakovlev, Messerschmitt Me 262s built by the Me 262 Project and Focke-Wulf Fw 190s by Flug Werk; this can include any one of a large number of different aircraft designs from between World War I the late 1930s, when military aircraft design was less complex. Such replicated warbirds may even be powered by vintage engines from the era of the aircraft design being flown, as Cole Palen did at his Old Rhinebeck Aerodrome aviation museum with accurate and airworthy reproductions of the Fokker Dr.I, Sopwith Camel and Sopwith Dolphin World War I aircraft.

Restoration process 
Vintage warbird restoration, or classic aircraft restoration, is the process of taking aircraft from the previous era, and performing processes such as maintenance, repairs and refurbishments in order to restore these military aircraft to their original wartime state (minus, of course, any working weaponry). According to Classic Warplanes, some of the tasks performed on these vintage aircraft include:
- Structural repairs
- Standard maintenance
- Interior and exterior paint
- Decals and stamps
- Upholstery replacements
- Control heads and radios
- Parachutes, ejection seats, and ejection seat cartridges
- Replacement of real weaponry with non-operating replicas

Some organizations in the United States are:
- Experimental Aircraft Association (EAA). The primary focus of the group started with building individual airplanes, and it soon grew to include antiques, classics, warbirds, aerobatic aircraft, ultralights, helicopters and contemporary manufactured aircraft.
- Warbirds of America (WOA) is a non-profit organization formed in 1964. A year after its start, it became a branch of the EAA.
- The Federal Aviation Administration (FAA) is the National aviation authority of the United States.
- Classic Jet Aircraft Association (CJAA)
