Letterkenny is distributed by Canadian video-on-demand service Crave, owned by Bell Media. It was the first original series offered on the platform. It is now also available for streaming in Australia and the United States, and on Region 1 DVD.
In Canada, all seasons and holiday specials can be streamed on Crave, on demand, with a subscription. Seasons 1–7 and the holiday specials can also be purchased from iTunes, Google Play, or Amazon Prime Video.
Crave also offers the Letterkenny: Ferda Edition, which includes episode commentary, and the original Letterkenny Problems series as well. Crave also streams the Littlekenny animated shorts offered by sister platform SnackableTV.
In the U.S., all seasons and holidays specials, as well as the Littlekenny shorts, are available for streaming on Hulu, on demand, with a subscription. On June 25, 2019, they were also made available in the U.S. iTunes store, and subsequently for purchase on Amazon Prime Video. The Ferda edition is not currently available in the U.S.
Seasons 1 and 2 were released on Hulu on July 13, 2018. Seasons 3–6 were released on Hulu at 3:00 a.m. Eastern Time on December 27, 2018. On June 6, 2019, Hulu announced that it had acquired exclusive streaming rights in the U.S., and would bill Letterkenny as one of its "Hulu Originals" starting with Season 7, to be released October 14. Despite this appellation, Hulu only distributes the show, and does not produce it.
On September 15, 2019, it was announced via @LetterkennyProb on Twitter that Letterkenny would be broadcast in Australia on free broadcast channel SBS Viceland starting on October 15, 2019, and also made available then through SBS On Demand. As of 2021, only seasons 1 through 6 are available from SBS, with no announcements made as to if and when seasons 7 and later will become available. Streams for seasons 1 through 7 are also available for purchase via iTunes.
On August 17, 2021, it was reported on Reddit that Letterkenny streams were available for purchase in the U.K. through Amazon Prime Video. Episodes from all nine seasons were available, but renumbered as if there were five seasons— seasons 3 through 5, 6 and 7, and 8 and 9, and their associated holiday specials being bundled together as seasons 3, 4, and 5.
Several Region 1 DVDs are available for sale from the Canadian and U.S. websites for Amazon.com. Although SBS began carrying Letterkenny in 2019, no Region 4 DVDs are available.
A disc has been released for each of the first eight seasons of Letterkenny. The Season 2 disc includes the St. Perfect's Day special, the Season 4 disc includes the The Haunting of MoDean's II special, and the Season 5 disc includes the Super Hard Easter special. The Season 6 DVD was released on August 27, 2019, the Season 7 DVD on February 4, 2020, and the Season 8 DVD on August 11, 2020.
A combined set, Letterkenny: Season 1-5, was made available in 2018. A collector's edition of this combined set came in a wooden box and included a Puppers beer cozy. A second box set, the Letterkenny Season 1–8 Collection, was released October 13, 2020. The DVDs are also sold in bundles, for seasons 1–7 and 1–8, though at a higher price than the box sets.
The DVDs are somewhat limited. They are not in high definition, do not include subtitles, and do not include the post-credits scenes from Season 1. They provide no special features or other additional content. Nevertheless, especially given the relatively limited distribution in the early days of the show, the DVDs were the most accessible way of watching legally.
