Battletruck (also known as Warlords of the 21st Century in the U.S. and Destructors in Italy) is a 1982 New Zealand post-apocalyptic science fiction action film co-written and directed by Harley Cokliss and starring Michael Beck, Annie McEnroe, James Wainwright, John Ratzenberger, and Bruno Lawrence.

Set in the aftermath of a devastating series of wars referred to as the Oil Wars, the plot is a futuristic tale of a community fighting against a local warlord in the lawless rural countrywide. A co-production between New Zealand and the United Kingdom, it was filmed on location in New Zealand and starring a number of local actors, and was part of a wave of similarly-themed films made in the wake of the success of the Mad Max series.
