The Bellanca YO-50 was a United States prototype observation aircraft, built for the United States Army in 1940. Typical for aircraft of its type, it was a high-wing braced monoplane with fixed tailwheel undercarriage and extensive cabin glazing. Its inverted "V" engine made it resemble its German equivalent, the Fieseler Storch.

Three examples were purchased for evaluation against the Stinson YO-49 and Ryan YO-51 Dragonfly. The Stinson won the production contract, and no further YO-50s were built.
