Knightmare is a British television programme for children and was broadcast on CITV from 7 September 1987 to 11 November 1994. An adventure game show, Knightmare involves a team of four children—one taking the role of the sightless dungeoneer, and the remaining three acting as their guide—traversing a medieval environment as they attempt to complete a quest and exit the dungeon, using their wits to overcome puzzles, obstacles and the unusual characters they meet along the journey.

The show is most noted for its use of blue screen chroma key (an idea borrowed by Tim Child from weather forecasts, where it had just started to be used) and use of 'virtual reality' interactive gameplay on television. Broadcast to high viewing figures throughout its original run, it has garnered a cult status amongst its fans since its final television episode in 1994. It was revived for a one off special by YouTube in August 2013.
