Robert de Flers (Robert Pellev? de La Motte-Ango, marquis de Flers) was a French playwright, opera librettist, and journalist.

He entered the Lyc?e 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.

De Flers was a member of the Acad?mie fran?aise from 1920 up until his death in 1927. He spent the last six years of his life as literary editor of Le Figaro, a position he was appointed to in 1921. He also served as the Conseiller G?n?ral of Loz?re during his latter years.
