The Henschel Hs 129 was a World War II ground-attack aircraft fielded by the German Luftwaffe. The aircraft saw combat in Tunisia and on the Eastern Front.

A key requirement of the original specification was that the aircraft be powered by engines that were not in demand for other designs. This limited it to low-power engines, with most models using a 700 horsepower (520 kW) French engine. In spite of being very small and relatively light, the design was generally underpowered. Attempts to fit more powerful engines, both German and Italian, were thwarted for a variety of reasons.

The design was relatively effective when it was first introduced, and saw service on the Eastern Front in a variety of front-line roles. As the war continued and anti-tank support became the main goal, the aircraft was continually up-gunned, eventually mounting a 75 mm gun in the anti-tank role that left the plane barely flyable. Only a small number of these B-3 models were produced, late in the war.
