Louis Delluc was an Impressionist French film director, screen writer and film critic.

He was born in Cadouin in 1890. His family moved to Paris in 1903. After graduating from the university, he became a literary critic. During the First World War, he was married to the Belgian actress Ève Francis, who acted in many of his films.

In 1917, Delluc began his career in film criticism. He went on to edit Le Journal du Ciné-club and Cinéa, establish film societies, and direct seven films. He was one of the early Impressionist filmmakers, along with Abel Gance, Germaine Dulac, Marcel L'Herbier, and Jean Epstein. His films are notable for their focus on ordinary events and the natural setting rather than on adventures and antics. Many of his early film writings for French newspapers were collected in the volume Cinema et cie (1919). He also wrote one of the first books on Charlie Chaplin (1921; translated into English in 1922).

Delluc directed his seventh film, L'Inondation (The Flood), in 1924. Filming took place in very poor weather conditions and Delluc contracted pneumonia. He died in Paris several weeks later, before the film was released.

The Prix Louis-Delluc, created in 1937, is named in his honour.
