Trailer Park Boys is a Canadian mockumentary television sitcom created by Mike Clattenburg that began airing in 2001 as a continuation of his 1999 film bearing the same name. The show follows the misadventures of a group of trailer park residents, including two lead characters in and out of prison, living in the fictional "Sunnyvale Trailer Park" in Dartmouth, Nova Scotia. The series premiered on Showcase on April 20, 2001, and originally ran for seven seasons before concluding with a one-hour special on December 7, 2008. The series spawned four films: The Movie, released on October 6, 2006; Countdown to Liquor Day, released on September 25, 2009; Don't Legalize It, released on April 18, 2014; and Standing on the Shoulders of Kitties: The Bubbles and the Shitrockers Story was released in December 2024.

In 2013, Robb Wells, John Paul Tremblay, and Mike Smith, the actors who respectively portrayed Ricky, Julian, and Bubbles, purchased the rights to the show from the original producers and created their own internet streaming network, SwearNet. Starting in March 2014, SwearNet co-produced new episodes of the show with the American streaming service Netflix, and the eighth season premiered on September 5, 2014. Several specials and mini-series were made in the years that followed. An animated spinoff series premiered on March 31, 2019. In October 2019, filming began on a spinoff series, Trailer Park Boys: Jail, which premiered on SwearNet on January 1, 2021.
