The Focke-Wulf A 33 Sperber (German: "Sparrowhawk") was a small airliner, produced in Germany in the early 1930s. It was a high-wing cantilever monoplane of conventional design, resembling a scaled-down version of the contemporary A 32 design. Only three examples were built, each purchased for air taxi duties with separate German airlines. One eventually briefly joined the fleet of Deutsche Luft Hansa in 1937.
