The Unbelievable Truth is a BBC radio comedy panel game devised by Graeme Garden and Jon Naismith. The game is chaired by David Mitchell and is described in the programme's introduction as 'the panel game built on truth and lies.' The object of the game is to lie about a subject, whilst also trying to include true statements without them being detected. The first series began broadcasting in 2007, and the 25th series was broadcast in early 2021.
