Dietrich Heinrich Ludwig Freiherr von Ompteda (5 March 1746, Hoya - 18 May 1803, Regensburg) was a Hanoverian jurist and government minister.

Dietrich Heinrich Ludwig von Ompteda was born in 1746 on his father's estate of Wulmstorf in the Hoya region.

He also educated his nephew Christian Friedrich Wilhelm von Ompteda, later an officer in the Napoleonic Wars.

Von Ompteda added a third sphere, Rechte und Verbindlichkeiten der Völker (Rights and liabilities of the peoples), which overrode the laws of war and peace and was only rarely influenced by them.

Other works by von Ompteda were published anonymously, since George III was regarded as very conservative and difficult and they dealt with the jurisdiction of the Holy Roman Empire, which were sometimes drastically changed by Napoleon.
