Jeux Descartes was a French publisher of roleplaying games and board games. Their most popular lines included: Eurogames, a set of serious board games, previously published by Duccio Vitale's independent company; Blue Games, small card games for larger groups; and Games for Two.

Jeux Descartes was founded in 1977 and went out of business in 2005. Their assets are now owned by former rival Asmodée Éditions, and are sold under the Descartes Editeur imprint.
