Assault on Dome 4 is a 1996 American science-fiction film directed by Gilbert Po and starring Joseph Culp, Bruce Campbell, Jocelyn Seagrave, and Brion James.

The film was written by Hesh Rephun.

Intergalactic extremist Alex Windham (Bruce Campbell) has seized control of Dome 4, a scientific outpost on another planet, after escaping from a penal colony on Mars.

Windham is forcing the staff of Dome 4 to construct new weapons that he can use to destroy his enemies, but he doesn't know that one of his captives is the wife of interstellar lawman Chase Moran (Joseph Culp) — and Moran will allow no harm to come to his wife.
