Teenagers from Outer Space (a.k.a. The Gargon Terror (UK title), The Boy from Outer Space, and originally titled The Ray Gun Terror) is a 1959 American independent black-and-white science fiction cult film released by Warner Bros. The film was produced, written and directed by Tom Graeff and stars David Love, Dawn Bender, Bryan Grant, Harvey B. Dunn, Tom Graeff and King Moody. Teenagers from Outer Space was distributed theatrically by Warner Bros. on a double feature with Gigantis the Fire Monster, the English-dubbed version of the 1955 Japanese giant monster film Godzilla Raids Again.

In the film, a young alien named Derek abandons his crew to search for a new life on Earth, while one of his crewmates is sent to find him as they attempt to eradicate human life in order to farm Earth with giant lobster-like livestock they call Gargons.

In 1987, the film entered the public domain in the United States because Warner Bros. did not renew its copyright registration in the 28th year after publication.
