The End of the F***ing World is a British black comedy television programme. Based on the 2011–13 minicomics The End of the Fucking World by Charles Forsman, the eight-part first series premiered its first episode on Channel 4 in the United Kingdom on 24 October 2017. Later episodes were released on All 4. Netflix handled international distribution and released it internationally on 5 January 2018. The programme follows James (Alex Lawther), a 17-year-old who believes himself to be a psychopath, and Alyssa Foley (Jessica Barden), an angry classmate who sees in James a chance to escape her tumultuous home life. Gemma Whelan, Wunmi Mosaku, Steve Oram, Christine Bottomley, Navin Chowdhry, Barry Ward and Naomi Ackie appear in supporting roles.

Series creator Jonathan Entwistle contacted Forsman about making a film, and a short one was made in 2014. The short film is now considered lost, with no way to access it online. Instead, an eight-part serial was commissioned, and filming began in April 2017. It was written by Charlie Covell and episodes were directed by Entwistle and Lucy Tcherniak. In August 2018, the programme was renewed for a second series, which premiered on Channel 4 on 4 November 2019, after which all eight episodes were released on All 4, and internationally on Netflix the next day. Before the second series's release, Covell said a third series was not planned.

The programme has been praised for its writing, execution and subject matter, as well as for Lawther's and Barden's performances. Both series were nominated for the British Academy Television Award for Best Drama Series, with the second series winning in 2020 and receiving a Peabody Award in 2019.

James is a 17-year-old who believes he is a psychopath. He kills animals as a hobby, but grows bored with that and decides to try killing a person. He settles on Alyssa, a mouthy, rebellious classmate with issues of her own. She proposes that they run away together, hoping for an adventure away from her turbulent home life, and James agrees with the intention of finding an opportunity to kill her. They embark on a road trip across England and develop a relationship after a series of mishaps.

"I made a short film of it six years ago with the majority of the people who are still involved — Jonathan Entwistle, who directed the film (and some of the series), and Dominic Buchanan, who’s a producer. At that point, Charlie hadn’t actually finished the comic, so I along with everyone else who was a fan of it, waited for them all to come out."—Jessica Barden, January 2018

The series was based on the work of the same title by Charles Forsman. Originally self-published as a series of mini-comics, the series was published as a graphic novel by Fantagraphics Books in 2013. It was republished in hardback in 2017, in anticipation of the television series.

While Forsman was publishing the mini-comics, Jonathan Entwistle contacted him about adapting it to a visual format – the original idea was to make an American film, and later a web series was considered. A film was pitched to Film4, and Entwistle was given funding for a short. Made in 2014, it featured some cast and crew who continued their roles for the television series. Entwistle directed and Dominic Buchanan was producer; Jessica Barden played Alyssa. However, instead of Alex Lawther, James was played by Craig Roberts.

Though the short was well-received, no production companies wanted to invest in the idea as a full-length film. Entwistle and Buchanan decided to make a television series with Clerkenwell Films, following which Channel 4 and then Netflix became involved. Forsman had no official role in the show's production, wanting to continue working on his comics, though Entwistle would regularly consult him and keep him updated. In August 2018, Channel 4's director of programmes Ian Katz expressed frustration that many people think the programme is a Netflix original, saying that "it's absolutely a Channel 4 show".
