Henning Alexander von Kleist (1676/77–1749) was an 18th-century Prussian field marshal. He fought in the War of Spanish Succession, the Great Northern War, and in the Wars of Austrian Succession. In particular, his actions at the Battle of Mollwitz brought him acclaim, although he had long been a stalwart supporter of Prussian military developments by the Prussian kings Frederick (1740–1786) and Frederick William I (1713–1740).
