The Deadly Spawn is a 1983 science fiction horror film directed by Douglas McKeown and starring Charles George Hildebrandt. In some territories, the film's title was changed to Return of the Aliens: The Deadly Spawn or The Return of the Alien's Deadly Spawn in an attempt to cash in on the worldwide success of Ridley Scott's 1979 film Alien.

It follows the story of a crash-landed alien that finds refuge in the basement of a house and grows to monstrous proportions, eating those unlucky enough to venture down. A handful of teenagers try to survive the onslaught of the creature and its young.
