Aeronca, contracted from Aeronautical Corporation of America, located in Middletown, Ohio, is a US manufacturer of engine components and airframe structures for commercial aviation and the defense industry, and a former aircraft manufacturer. From 1928 to 1951, the company was a major producer of general aviation aircraft, and also produced the engines for some of their early designs.  Aeronca is now (2011) a division of Magellan Aerospace, producing aircraft, missile, and space vehicle components at the same location adjacent to Middletown’s Hook Field Municipal Airport.

The Aeronca Aircraft Corporation was founded November 11, 1928, in Cincinnati, Ohio. Backed by the financial and political support of the prominent Taft family and future Ohio senator Robert A. Taft who was one of the firm's directors, Aeronca became the first company to build a commercially successful general aviation aircraft.  When production ended in 1951, Aeronca had sold 17,408 aircraft in 55 models. Aeronca C-2 registered CF-AOR in the Canada Aviation Museum, Rockcliffe (Ottawa) Ontario, 2006 Production began with the Jean A. Roche-designed Aeronca C-2 monoplane, often called the "Flying Bathtub", in 1929. The next major model was the Scout of 1937, a two-seater, which was developed into the Chief and Super Chief the next year. In 1937 there was a major flood at the Lunken Airport, resulting in the entire airport area being washed away. Aeronca's factory was destroyed, along with the tooling and almost all of the very early blueprints and drawings. At this time a decision was made to move the operation to a more stable area. Middletown, Ohio, was chosen, and the company has remained there ever since.  All of the airplanes produced from the start of production in 1929 to 1937 are known as the "Lunken" Aeroncas. The first Aeronca built in Middletown was produced on June 5, 1940, and after this time all Aeroncas were built here.

Aeronca ceased light aircraft production in 1951, and in 1954 sold the Champion design to the new Champion Aircraft Corporation of Osceola, Wisconsin, which continued building variants of the Champion as well as the derivative design, the Citabria. The venerable aircraft design was acquired again by the Bellanca Aircraft Company in 1970 and again to American Champion in 1988, where it remains in production.  In the early 1970s, Aeronca was contracted by Bede Aircraft to assemble its first Bede BD-5J Microjet—the world's smallest jet airplane—but, after its experiences with the prototype, Aeronca declined to be further involved with the program. In 1978 Aeronca planned to start aircraft production again with production of a prototype very light business jet, the Foxjet ST600. The project was eventually cancelled due to lack of WR-44 engine availability. Aeronca now builds components for aerospace companies including Boeing, Northrop Grumman, Lockheed and Airbus. In its 23-year history as a general aviation and military aviation manufacturer, Aeronca produced 17,408 aircraft spanning 55 different models.
