American Chopper: The Series is a Learning Channel reality television series produced by Pilgrim Films & Television Inc., and a video game published by Activision. This popular series is based around the founder of the company, Paul Teutul, Sr., and his son, Paul Teutul, Jr., also known as Paulie, as the two run a business creating custom motorcycles in their workshop, Orange County Choppers. The workshop is based in Montgomery, New York. One of their most famous bikes is the Black Widow Spider Bike.

The contrasting attitudes of the men and their propensity for sulking often lead to fiery but humorous verbal exchanges as they meet unusually short schedule deadlines for building distinct custom choppers.

Originally a show on the Discovery Channel, the series moved to Discovery's sister channel, TLC, on December 28th, 2006, starting off with an 18-hour marathon. Its first season on TLC premiered on January 18, 2007.
