Sir Jacques Le Gris (c. 1330s – 27 December 1386) was a squire and knight in fourteenth century France who gained fame and infamy when he engaged in the last judicial duel permitted by the Parlement of Paris after he was accused of rape by the wife of his neighbour and rival Sir Jean de Carrouges. Carrouges brought legal proceedings against Le Gris before King Charles VI who after hearing the evidence, authorised a trial by combat to determine the question. The duel attracted thousands of spectators and has been discussed by many notable French writers, from the contemporary Jean Froissart to Voltaire.
