Sir Jean de Carrouges IV (c. 1330s – 25 September 1396) was a French knight who governed estates in Normandy as a vassal of Count Pierre d'Alençon and served under Admiral Jean de Vienne in several campaigns against the English and the forces of the Ottoman Empire. He became infamous in medieval France for fighting in the last judicial duel permitted by the French king and the Parlement of Paris. The combat was decreed in 1386 to contest charges of rape Carrouges had brought against his neighbour and erstwhile friend Jacques Le Gris on behalf of his wife Marguerite. It was attended by much of the highest French nobility of the time led by King Charles VI and his family, including a number of royal dukes. It was also attended by thousands of ordinary Parisians and in the ensuing decades was chronicled by such notable medieval historians as Jean Froissart, Jean Juvénal des Ursins and Jean de Waurin.
