The Most Extreme is a documentary television series on the American cable television network Animal Planet. It first aired on July 7, 2002. Each episode focuses on a specific animal feature, such as strength, speed, behavior, anatomy, or diet, and examines and ranks ten animals that portray extreme or unusual examples of that quality. Along with each animal on the countdown, each episode presents an animated segment which compares the animal's ability with something equivalent in humans, followed by an interview segment with people who share some common trait. Old, often public domain, cartoons, movie clips and trailers are often included.

"Earth is a planet of extremes. Extreme places, and extreme animals. But some animals are more extreme than others. Join us as we count down to find the most unusual, the most extraordinary, The Most Extreme."

— Opening of the show.

The show was narrated by Adam J. Harrington. On Animal Planet, the episodes were also announced by Simon Arnstein.
