The Desert Within (Spanish: Desierto Adentro) is a 2008 Mexican drama film written and directed by Rodrigo Plá. The film was inspired by the diaries of the Christian existentialist philosopher Søren Kierkegaard. It won seven awards at the 2008 Guadalajara International Film Festival. The film incorporates animation and art as bookends to each series of events in the film.

The title of the film is drawn from Nietzsche's epigraph about acknowledging uncertainty: "The desert grows, and woe to him who conceals the desert within him..."
