Deep Impact is a 1998 American science fiction disaster film directed by Mimi Leder, written by Bruce Joel Rubin and Michael Tolkin, and starring Robert Duvall, Téa Leoni, Elijah Wood, Vanessa Redgrave, Maximilian Schell, and Morgan Freeman. Steven Spielberg served as an executive producer of this film. It was released by Paramount Pictures in North America and by DreamWorks Pictures internationally on May 8, 1998. The film depicts humanity's attempts to prepare for and destroy a 7-mile (11 km) wide comet set to collide with Earth and cause mass extinction.

Deep Impact was released in the same summer as the similarly themed Armageddon, which fared better at the box office, while astronomers described Deep Impact as being more accurate. Deep Impact was slightly better received critically than Armageddon, although both ultimately received mixed reviews. Deep Impact grossed over $349.5 million worldwide on an $80 million production budget, becoming the sixth highest-grossing film of 1998.

It was the final film by cinematographer Dietrich Lohmann, who died before the film's release.
