The Douglas DC-8 (also known as the McDonnell Douglas DC-8) is a four-engine long-range narrow-body jet airliner built from 1958 to 1972 by the Douglas Aircraft Company. Launched after the competing Boeing 707, the DC-8 nevertheless kept Douglas in a strong position in the airliner market, and remained in production until 1972 when it began to be superseded by larger wide-body designs, including the Boeing 747, McDonnell Douglas DC-10 and Lockheed L-1011 TriStar. The DC-8's design allowed it a slightly larger cargo capacity than the 707 and some re-engined DC-8s are still in use as freighters.

After World War II Douglas had a commanding position in the commercial aviation market. Boeing had pointed the way to the modern all-metal airliner in 1933 with its Model 247, but Douglas, more than any other company, made commercial air travel a reality. Douglas produced a succession of piston-engined aircraft (DC-2, DC-3, DC-4, DC-5, DC-6, and DC-7) through the 1930s, 1940s, and 1950s. When de Havilland flew the first jet airliner, the Comet, in 1949, Douglas felt no need to rush into anything new. Their U.S. competitors at Lockheed and Convair felt the same way: that there would be a gradual switch from piston engines to turbines, and that the switch would be to the more fuel-efficient turboprop engines rather than pure jets. All three companies were working on a new generation of piston-engined designs, with an eye to turboprop conversion in the future.
