Charles Chalmot de Saint-Ruhe (c. 1650 – 12 July 1691) was a French cavalry officer, serving in the armies of Louis XIV.

Despite a long career, Saint-Ruhe is remembered largely for his brief service in Ireland during the Williamite War, in which France provided military support to the Jacobite forces of James II. While in command of James's Irish Army, he was killed at the Battle of Aughrim, a defeat that led to the collapse of the Jacobite cause.
