This article covers all the known deleted scenes from the 1979 film Alien. Some of these sequences never progressed past the early script or storyboard stages, while others were filmed before being cut during the editing process. Despite their removal, several of these scenes were included in the movie's novelization and the comic book adaptation. Aside from the scenes described below, the film also had blood and gore trimmed throughout. There was talk of this censored violence footage being reintegrated into an uncut release of the film, although as of yet that has not occurred.
