The Boeing 747 is a widebody commercial airliner, often referred to by the nickname Jumbo Jet. It is among the world's most recognizable aircraft, and was the first widebody ever produced. Manufactured by Boeing's Commercial Airplane unit in the United States, the original version of the 747 was two and a half times the size of the Boeing 707, one of the common large commercial aircraft of the 1960s. First flown commercially in 1970, the 747 held the passenger capacity record for 37 years.

The four-engine 747 uses a double deck configuration for part of its length. It is available in passenger, freighter and other versions. Boeing designed the 747's hump-like upper deck to serve as a first class lounge or (as is the general rule today) extra seating, and to allow the aircraft to be easily converted to a cargo carrier by removing seats and installing a front cargo door. Boeing did so because the company expected supersonic airliners (whose development was announced in the early 1960s) to render the 747 and other subsonic airliners obsolete; while believing that the demand for subsonic cargo aircraft would be robust into the future. The 747 in particular was expected to become obsolete after 400 were sold but it exceeded its critics' expectations with production passing the 1,000 mark in 1993. As of September 2023, 1,574 aircraft have been built, with the final delivery in January 2023.

The 747-8, the latest version in service, is among the fastest airliners in service with a high-subsonic cruise speed of Mach 0.855 (564 mph or 908 km/h). It has an intercontinental range of 7,730 nautical miles (14,320 km; 8,900 mi). The 747-8I (passenger version) can accommodate 467 passengers in a typical three-class layout. The 747-8 completed production on 6 December 2022 and the final 747 was delivered to Atlas Air on 31 January 2023.
