Charles de Rohan, 4th Prince of Soubise, Prince of Soubise, Duke of Rohan-Rohan, Seigneur of Roberval, and Marshal of France from 1758, was a soldier, and minister to kings Louis XV and Louis XVI. He was the last male of his branch of the House of Rohan, and was great-grandfather to the Duke of Enghien, executed by Napoleon in 1804. Styled Prince d'Epinoy at birth, he became the Prince of Soubise after 1749.

Marshal of France is a French military distinction, rather than a military rank, that is awarded to generals for exceptional achievements. The title has been awarded since 1185, though briefly abolished (1793–1804) and for a period dormant (1870–1916). It was one of the Great Officers of the Crown of France during the Ancien Régime and Bourbon Restoration, and one of the Grand Dignitaries of the Empire during the First French Empire.
