Eustache Deschamps (1340–1406) is a medieval French poet, also known as Eustache Morel.

Born at Vertus, in Champagne, he receives lessons in versification from Guillaume de Machaut and later studies law at Orleans University.

He then travels through Europe as a diplomatic messenger for Charles V. His estate is pillaged by the English, in consequence of which he continuously abuses them in his many poems.
