De Mol (The Mole) is a Belgian reality game show that originally aired from 6 December 1998 to 19 March 2000 and again from 19 January to 16 March 2003 on TV1 with Michiel Devlieger as host. A revival has aired since 1 February 2016 on VIER with Gilles De Coster as host. The show won the famous Rose d'Or award in 2000. The format has been licensed in 40 countries from all around the world.

Players in The Mole must work together to complete various physical and mental challenges to build up a significant prize for the winner. One of them, however, is "the Mole", a double agent hired by the producers to sabotage the efforts of the group. The Mole must be careful to avoid drawing too much suspicion to himself or herself. Using journals, players must track vast amounts of data about the person(s) they suspect of being the Mole, such as seating positions, clothing colors, minor discussion topics, and so on. The quiz at the end of each episode tests players' knowledge of the Mole, and determines by lowest score (or slowest time, in the event of a tie) who is eliminated from the game.
