American Chopper is a reality television series that airs on Discovery Channel, produced by Pilgrim Films & Television. The series centers on Paul Teutul, Sr. (frequently called Senior), and his son Paul Teutul, Jr. (also known as Paulie or simply Junior), who manufacture custom motorcycles. Orange County Choppers is in Newburgh, New York. The contrasting attitudes of the two men and their propensity for argument often lead to heated exchanges as they meet unusually short deadlines for building distinctive custom choppers.

Originally aired on Discovery Channel beginning in March 2003. In December 2007 the series moved to Discovery's sister channel TLC, starting off with an 18-hour marathon. Its first TLC season premiered in January 2008. Season 6 began in April 2009 but the series was canceled by TLC in February 2010. In July 2010 TLC announced that the Teutuls would return in a new series, American Chopper: Senior vs. Junior. Senior vs. Junior premiered on TLC but was soon moved to Discovery halfway through the first season.
