French novelist whose works provide a lighthearted, licentious, and satirical view of 18th-century high society in France.

The son of an outstanding French poet-dramatist, Prosper Jolyot de Crébillon (Crébillon, Prosper Jolyot, sieur de), he displayed a completely different temperament from that of his father (who heartily disapproved of his son's life and works). Crébillon fils spent all his life in Paris except for two periods of exile in the provinces as a result of satirical allusions in his novels. Of these novels, the best known are L'écumoire (1735; The Skimmer), Les Égarements du coeur et de l'esprit (1736; The Wayward Head and Heart), and Le Sopha, conte moral (1742; The Sofa; A Moral Tale). These novels were appreciated by Laurence Sterne, who saw in the writing some of his own inconsequential narrative style.

Along with this literary activity, Crébillon was a founder in 1729 of the Société du Caveau, named after a cafe in which he and his friends dined, where Crébillon earned a reputation as a wit and storyteller. Like his father he enjoyed the patronage of Mme de Pompadour.
