The Last Starfighter is a 1984 American space opera film directed by Nick Castle. The film tells the story of Alex Rogan (Lance Guest), a teenager recruited by an alien defense force to fight in an interstellar war. It also features Robert Preston, Dan O'Herlihy, Catherine Mary Stewart, Norman Snow, and Kay E. Kuter.

The Last Starfighter, along with Disney's Tron, has the distinction of being one of cinema's earliest films to use extensive "real-life" computer-generated imagery (CGI) to depict its many starships, environments, and battle scenes.

The Last Starfighter was Robert Preston's final role in a theatrical film. The character of Centauri, a "lovable con-man", was written with him in mind and was a nod to his most famous role as Professor Harold Hill in The Music Man.There was a subsequent novelization of the film by Alan Dean Foster, as well as a video game based on the production. In 2004, it was also adapted as an off-Broadway musical.
