The Douglas A-1 Skyraider (formerly AD) is an American single-seat attack aircraft that saw service between the late 1940s and early 1980s. The Skyraider had a remarkably long and successful career; it became a piston-powered, propeller-driven anachronism in the jet age, and was nicknamed "Spad", after the French World War I fighter.

It was operated by the United States Navy (USN), the United States Marine Corps (USMC) and the United States Air Force (USAF), and also saw service with the British Royal Navy, the French Air Force, the Air Force of the Republic of Vietnam (VNAF), and others. In U.S. service, it was finally replaced by the LTV A-7 Corsair II swept wing subsonic jet in the early 1970s.

The piston-engined Skyraider was designed during World War II to meet United States Navy requirements for a carrier-based, single-seat, long-range, high performance dive/torpedo bomber, to follow-on from earlier types such as the Helldiver and Avenger. Designed by Ed Heinemann of the Douglas Aircraft Company, prototypes were ordered on 6 July 1944 as the XBT2D-1. The XBT2D-1 made its first flight on 18 March 1945 and in April 1945, the USN began evaluation of the aircraft at the Naval Air Test Center (NATC). In December 1946, after a designation change to AD-1, delivery of the first production aircraft to a fleet squadron was made to VA-19A.
