Quiz is a British drama television serial developed for the ITV channel and AMC and written by James Graham, based on his play of the same name commissioned by William Village and the book Bad Show: the Quiz, the Cough, the Millionaire Major by Bob Woffinden and James Plaskett. It is directed by Stephen Frears and consists of three hour-long episodes. The series focuses on the Who Wants to Be a Millionaire? contestant Charles Ingram, a former army major in the Royal Engineers, and how he unexpectedly won the £1 million jackpot on the quiz show in 2001, followed by a criminal trial in which he and his wife were convicted of cheating their way to success.

Quiz premiered on ITV on 13 April 2020. The series received positive reviews from critics. Released during the height of the COVID-19 pandemic lockdowns worldwide, Quiz received a large audience — similar to the Netflix documentary Tiger King — with the first episode being seen live by an average audience of 5.3 million in the UK. While the show was still airing, Ingram's Wikipedia article was one of the most viewed on the site.
