The Airspeed AS.5 Courier was a British six-seat single-engined light aircraft that was designed and produced by the British aircraft manufacturer Airspeed Limited at Portsmouth. It has the distinction of being the first British aircraft fitted with a retractable undercarriage to go into quantity production.

Airspeed Limited was established in 1931 to build aeroplanes in York, England, by A. H. Tiltman and Nevil Shute Norway. The other directors were A. E. Hewitt, Lord Grimthorpe and Alan Cobham. Amy Johnson was also one of the initial subscribers for shares.
