Invaders from Mars is a 1986 American science fiction horror film directed by Tobe Hooper from a screenplay by Dan O'Bannon and Don Jakoby, and starring Hunter Carson, Karen Black, Timothy Bottoms, Laraine Newman, James Karen, Bud Cort and Louise Fletcher. It is a remake of the 1953 film of the same name.

The film was part of a three-picture deal between Hooper and Cannon Films. Its production was instigated by Wade H. Williams III, millionaire exhibitor, science fiction film fan and sometime writer-producer-director, who had reissued the original film in 1978 after purchasing the copyright to the property. Elaborate creature and visual effects were supplied by Stan Winston and John Dykstra. The score was composed by Christopher Young and Dave Storrs.

The film was released in the United States on June 6, 1986. It received mixed-to-negative reviews from critics and was a box-office disappointment, though in the years since its release it has developed a cult following.
