Thunder Rock is a 1942 British drama film directed by Roy Boulting and starring Michael Redgrave and Barbara Mullen, with James Mason and Lilli Palmer in supporting roles. It was based on Robert Ardrey's 1939 play Thunder Rock.

John Edward Boulting and Roy Alfred Clarence Boulting, known collectively as the Boulting brothers, were English filmmakers and identical twins who became known for their series of satirical comedies in the 1950s and 1960s. They produced many of their films through their own production company, Charter Film Productions, which they founded in 1937.
