The Beechcraft Bonanza is an American general aviation aircraft introduced in 1947 by Beech Aircraft Corporation of Wichita, Kansas. The six-seater, single-engined aircraft is still being produced by Beechcraft and has been in continuous production longer than any other aircraft in history. More than 17,000 Bonanzas of all variants have been built, produced in both distinctive V-tail and conventional tail configurations; early conventional-tail versions were marketed as the Debonair.

Beechcraft is an American brand of civil aviation and military aircraft owned by Textron Aviation since 2014, headquartered in Wichita, Kansas. Originally, it was a brand of Beech Aircraft Corporation, an American manufacturer of general aviation, commercial, and military aircraft, ranging from light single-engined aircraft to twin-engined turboprop transports, business jets, and military trainers. Beech later became a division of Raytheon and then Hawker Beechcraft before a bankruptcy sale turned its assets over to Textron. It remains a brand of Textron Aviation.
