Anders Rudolf du Rietz (pronounced [dyrié]; 5 February 1722 – 21 October 1792 in Hedensberg, Västmanland) was a Swedish count, lieutenant-general, commander grand cross of the Order of the Sword, County Governor and politician.

[1] du Rietz began his military career as a lieutenant in the Life Guards and was sent to the Finnish front in the Russo-Swedish War (1741–1743) with that regiment.

He won distinction in this war, capturing the Anclamen Feler fort, protecting the Swedish siege of Peenemünde and obtaining the advantageous capitulation of the Prussian forces at Demmin by Field Marshal Johann von Lehwaldt.

During this political career he was also promoted to colonel and to become head of the Hälsinge Regiment, and shortly afterwards was sent to bear the Swedish official congratulations on Catherine II of Russia's accession.

Towards the end of his life, he was suspected of laziness in the defence of Gothenburg during the Russo-Swedish War (1788–1790), though Gustav III arrived in time to save the city.
