Robert de Flers (Robert Pellevé de La Motte-Ango, marquis de Flers) (25 November 1872, Pont-l'Évêque, Calvados – 30 July 1927, Vittel) was a French playwright, opera librettist, and journalist. He entered the Lycée Condorcet in 1888 where he studied law with the initial ambition of entering diplomatic service. He met and befriended fellow student and writer Marcel Proust, and that relationship had a great influence upon him. Proust exposed Flers to art, literature, and music and his interests soon switched from law to writing, journalism, and literature. The two men enjoyed a lifelong friendship.
