Heino Heinrich Reichsgraf von Flemming (8 May 1632 - 1 March1706) was a Saxon, later Brandenburger army leader and Field Marshal and Governor of Berlin.

Flemming came from an old noble Brandenburg family that probably emigrated from the Netherlands. After a comprehensive education at German universities, Flemming fought the Turks as a Colonel of Auxiliary Troops in the service of Brandenburg, Elector Frederick Wilhelm sent him to the King of Poland in 1672. After serving William of Orange excellently several times, Flemming eventually came to serve in the Brandenburg army, although in times of peace he served in other armies. Because of his ability and bravery he received many offers to change services, and in 1682 became a Feldmarschallleutnant (roughly the equivalent of a four-star general) in the Saxon army. Commanding Saxon auxiliary troops, he contributed to the delaying of the Turks before Vienna in 1683.

On 15 February 1684 he became commander of Saxon troops and became a Field Marshal after the death of Baron von der Goltz on 8 September 1688.

In this and the following year he commanded the Saxon troops on the Rhine under Elector George III. However, he was suspended for multiple personal offenses, which hurt him deeply. The Austrian generals accused him of corruption. He left the Saxon army and became a marshal with the Brandenburg army, one of four field marhals who did so (the other three being Johnn Georg II of Dessau, Derfflinger, and Spaen). Flemming commanded successfully in Flanders and retired in 1698 for health reasons.
