When Time Ran Out... is a 1980 American disaster film directed by James Goldstone and starring Paul Newman, Jacqueline Bisset and William Holden. The supporting cast features James Franciscus, Ernest Borgnine, Red Buttons, Burgess Meredith, Valentina Cortese, Veronica Hamel, Pat Morita, Edward Albert and Barbara Carrera.

Produced by Irwin Allen, When Time Ran Out...'s screenplay by Carl Foreman and Stirling Silliphant is marginally based on the 1969 novel The Day the World Ended by Gordon Thomas and Max Morgan-Witts detailing the factual 1902 volcanic eruption of Mount Pelée on Martinique, which killed 30,000 people in five minutes by pyroclastic flow.

It marked the second and final time Newman and Holden appeared in a film together following the box office triumph of The Towering Inferno six years prior, as well as reuniting Borgnine and Buttons from The Poseidon Adventure. When Time Ran Out..., however, was a commercial flop and Allen's last theatrical release and is often regarded as the final 1970s era disaster film. The film was a critical and commercial disappointment. Paul Zastupnevich's work on the film was recognized by a nomination for the Academy Award for Best Costume Design .
