The Inbetweeners is a British coming-of-age television teen sitcom, which originally aired on E4 from 2008 to 2010 and was created and written by Damon Beesley and Iain Morris. The series follows the misadventures of suburban teenager William McKenzie (Simon Bird) and his friends Simon Cooper (Joe Thomas), Neil Sutherland (Blake Harrison) and Jay Cartwright (James Buckley) at the fictional Rudge Park Comprehensive. The programme involves situations of school life, uncaring school staff, friendship, male bonding, lad culture and adolescent sexuality. Despite receiving an initially lukewarm reception, it has been described as a classic and amongst the most successful British sitcoms of the 21st century.

The programme was nominated for Best Situation Comedy at BAFTA twice, in 2009 and 2010. At the British Academy Television Awards 2010, it won the Audience Award, the only category voted for by the public. In the 2011 British Comedy Awards, the programme also won the award for Outstanding Contribution to British Comedy.

The Inbetweeners Movie was released on 17 August 2011 to box office success, and a sequel followed on 6 August 2014. An American version was broadcast on MTV, but was quickly axed after low ratings and poor critical reception.
