Naked Jungle was a one-off television gameshow produced for the United Kingdom terrestrial TV station Channel 5 by Yorkshire Television, airing on 6 June 2000. A gameshow with an assault course format, based on and using the same set as the children's show Jungle Run, it was controversial because its contestants were nudists. The programme's presenter, Keith Chegwin, was also naked, except for a hat. It was part of a special season of programmes on the channel to mark the 50th anniversary of British naturism.
