Manufacturer: Ryan Aeronautical
First flight: 1940
Primary user: U.S. Army Air Force
Number built: 3

The YO-51 Dragonfly was a United States prototype observation aircraft built for the US Army by Ryan Aeronautical. Typical for aircraft of its type, it was a high-wing braced parasol wing monoplane with fixed tailwheel undercarriage, a two-seat open cockpit, and full-span slots and Fowler flaps for STOL capability.

At gross weight, the YO-51 could, without flaps, take off after a run of 400 feet, while with full flaps the take off run would be only 75 feet, or just four feet more than twice its own length.

Three examples were purchased for evaluation against the Stinson YO-49 and Bellanca YO-50. The Stinson machine won the production contract and no further YO-50s were built.
