Letterkenny is a Canadian television sitcom created by Jared Keeso and directed by Jacob Tierney, both of whom are also its developers and primary writers. It premiered via Crave on February 7, 2016, and concluded on December 25, 2023. The series follows the adventures of people residing in the fictional rural Ontario community of Letterkenny and stars Keeso, Nathan Dales, Michelle Mylett, and K. Trevor Wilson.

Adapted from a YouTube series called Letterkenny Problems, the show was commissioned by Crave in March 2015. It is distributed by Hulu in the United States, with the first two seasons debuting in July 2018. Subsequent seasons were added on December 27, 2018. Hulu acquired exclusive U.S. streaming rights in May 2019. The 12th and final season was released on December 25, 2023.

The show has received numerous awards and nominations, including a Canadian Screen Award for Best Comedy Series. A spin-off series created by and starring Keeso, Shoresy, debuted via Crave in 2022.

Letterkenny revolves around the titular rural Ontario community, which took its name from Letterkenny in Ireland and is populated mostly by the descendants of Irish immigrants who escaped to Canada during the Great Famine.^[1] The majority of episodes open with text stating, "There are 5000 people in Letterkenny. These are their problems." The series focuses on siblings Wayne and Katy, who run a small farm and produce stand with help from Wayne's friends Daryl and Squirrely Dan.

Episodes deal with small-town life amongst different types of people: the farmers ("Hicks"), gym goers and out-of-towners who play for the local ice hockey team ("Jocks"), the town's obviously closeted Christian minister Glen, the drug addicts ("Skids"), members of the nearby First Nation reservation ("Natives"), the neighbouring Mennonites, and the Québécois. Early plots often revolved around Wayne defending his reputation as "the toughest guy in Letterkenny", the town's unsuccessful ice hockey team, the Skids' schemes to rip everyone off for drug money, and Wayne's dating life after dumping his high school sweetheart who cheated on him.

Each episode begins with a cold open presented in a mockumentary style with characters speaking directly to the camera, which is intercut with a regular sitcom format depicting the scenario the characters are describing; after the opening title sequence, this mockumentary style is abandoned and the camera is never addressed again. The show has been praised for subverting the trope of small-town residents being portrayed as narrow-minded and unintelligent; this is most commonly exemplified by the running joke that almost all characters express sophisticated and informed views on social issues and can produce a constant flow of one-liners, puns, comebacks, and wordplay when in conversation with each other.

Letterkenny is filmed in Sudbury, Ontario.^[2] It is the first original series commissioned by Crave,^[3] and premiered on that platform on February 7, 2016.^[4] The town of Letterkenny portrayed in the series is fictional and is not based on the real Letterkenny in Ontario, which is now part of Brudenell, Lyndoch and Raglan.^[5] The town in the show is instead loosely based on Keeso's hometown of Listowel, Ontario.^[6]

The show has its roots in Letterkenny Problems, a short-form web series created by Keeso and released on YouTube in 2013.^[7] The original Letterkenny Problems consisted almost entirely of Keeso and Dales trading off comedic one-liners while simply standing in various locations, a theme that would later resurface as the intro to some Letterkenny episodes.^[8] Letterkenny Problems garnered a Canadian Screen Award nomination for Best Original Fiction Program or Series Created for Digital Media at the 2nd Canadian Screen Awards in 2014.^[3]
