Coupling is a British television sitcom written by Steven Moffat that aired on BBC Two and BBC Three from 12 May 2000 to 14 June 2004. Produced by Hartswood Films for the BBC, the show centres on the dating, sexual adventures, and mishaps of six friends in their early 30s, often depicting the three women and the three men each talking among themselves about the same events, but in entirely different terms.

The series was inspired by Moffat's relationship with producer Sue Vertue, to the extent that they gave their names to two of the characters. Coupling is an example of the "group-genre", an ensemble show that had proven popular at the time. Critics compared the show to the American sitcoms Friends and Seinfeld.

The critical reaction was largely positive, and the show was named "Best TV Comedy" at the 2003 British Comedy Awards. The show debuted to unimpressive ratings, but its popularity soon increased, and by the end of the third series, the show had achieved respectable ratings in the UK. The series first aired on PBS stations and on BBC America in the United States beginning in late 2002 and quickly gained a devoted fanbase there, as well. The show is syndicated around the world. Short-lived American and Greek adaptations were briefly produced in 2003 and 2007, respectively. In a 2004 poll to find Britain's Best Sitcom, Coupling came in 54th.
