Room 101 is a BBC television series in which celebrities are invited to discuss their (often whimsical) pet hates with the host. If the host is sympathetic to the argument, he will consign the object of their hatred to "Room 101", an imaginary repository of everything bad and hateful, in a reference to the Orwellian meaning of the term.

The series was originally broadcast on BBC Radio 5 where it was hosted by Nick Hancock. Hancock was also the first presenter when the series transfered to television. He later left the series and was replaced by the current host, Paul Merton.
