The Focke-Wulf A 17 Möwe (German: "Gull") was an airliner built in Germany in the late 1920s. It was a conventional high-wing cantilever monoplane with fixed tailwheel undercarriage. The aircraft provided fully enclosed seating for up to eight passengers and had a separate, fully enclosed flight deck for the two pilots. Most examples flew with Deutsche Luft Hansa, serving until around 1936. In the early 1930s, two A 17s were used for testing the Junkers Jumo 5 diesel engine.

In 1929, an example was built with a BMW VI engine and fitted out for aerial photography and survey work and designated A 21. The cabin was equipped with a darkroom. Later the same year, the BMW engine was used on a further five airliners for Luft Hansa, these being designated A 29.
