Eustache Deschamps (1340–1406) was a medieval French poet, also known as Eustache Morel (, 699). Born at Vertus, in Champagne, he received lessons in versification from Guillaume de Machaut and later studied law at Orleans University. He then traveled through Europe as a diplomatic messenger for Charles V, being sent on missions to Bohemia, Hungary and Moravia. In 1372 he was made huissier d’armes to Charles. He received many other important offices, was bailli of Valois, and afterwards of Senlis, squire to the Dauphin, and governor of Fismes.
