Weakest Link (also known as The Weakest Link) is a television game show which first appeared in the United Kingdom on BBC Two on 14 August 2000 and originally ended on 31 March 2012 when its host Anne Robinson completed her contract. The original British version of the show is still aired around the world on BBC Entertainment. The game begins with a team of eight or nine contestants who take turns answering general knowledge questions within a time limit to create chains of correct answers in a row. At the end of each round, the players vote one contestant, "The Weakest Link", out of the game. Once two players are left, they play in a head-to-head contest, with five questions asked to each contestant in turn, to determine the winner.

The format has been licensed across the world, with many countries producing their own series of the programme and is the second most popular international franchise, behind only the Who Wants to Be a Millionaire? franchise, which also originated in the UK.
