René Fauchois (31 August 1882 – 10 February 1962) was a French dramatist, librettist and actor. Stagestruck from his youth he moved from his native Rouen to Paris as a teenager to pursue a stage career. He had early success both as an actor and as a playwright. Among those with whom he collaborated as his career flourished were Sarah Bernhardt and Sacha Guitry. His career lasted for more than sixty years, and his output was prolific. As a librettist Fauchois is probably best known for writing the "poème lyrique" for Fauré's Pénélope (1913). His best-known play is Prenez garde à la peinture (1932), a comedy of bourgeois avarice, adapted for US and British stage and screen as The Late Christopher Bean. His 1919 comedy Boudu sauvé des eaux has been filmed in both French and English.
