Roger Planchon (born 12 September 1931 in Saint-Chamond, Loire, died on 12 May 2009 in Paris), was a French playwright, director, and filmmaker.

Roger Planchon spent his childhood in the Ardèche, notably in Dornas. He found its inspiration from his rural origins and this issue was a recurring theme in his writings.

He started on stage in 1949 after winning an amateur theater. In 1952, he founded the Théâtre de la Comédie, located in the rue des Marronniers, in Lyon. He was the director of the Théâtre de la Cité of Villeurbanne since 1957 (which became the Théâtre National Populaire in 1972).

Roger Planchon transposed many works by Brecht, Molière, Shakespeare, and many works of contemporary authors, including Arthur Adamov and Michel Vinaver, but also opened the Théâtre National Populaire to Patrice Chéreau, then Georges Lavaudant.

As films, he directed George Dandin ou le Mari confondu by Molière, Louis, enfant roi, which was entered at Cannes,^[1] and another one by Lautrec.
