The Incredible Petrified World is a 1959 science fiction film produced and directed by Jerry Warren, and starring John Carradine and Robert Clarke. The film follows four explorers who travel down into the depths of the sea and get stranded in an underwater cavern.

The film was completed by Warren in 1957, but remained unreleased until it was distributed in Texas and other Southern states starting in November 1959 and, more widely, in April 1960 on a double feature with Warren's Teenage Zombies.
