Explorers is a 1985 American science fantasy film written by Eric Luke and directed by Joe Dante. The film stars Ethan Hawke and River Phoenix, both in their film debuts, and Jason Presson as young teenage boys who build a spacecraft to explore outer space. The special effects were produced by Industrial Light & Magic, with make-up effects by Rob Bottin.

Rushed into production, the film was never properly finished. Dante revealed that the studio demanded that he stop editing and rush for a July release where it was overshadowed by the Live Aid concert, which was held one day after the film's release and stiff competition from Back to the Future, which opened nine days prior. It was a box office failure upon its release, but it attracted a cult following with its VHS release.
