Mastermind is a British television quiz show for the BBC, currently presented by Clive Myrie. Its creator, Bill Wright, drew inspiration from his experiences of being interrogated by the Gestapo during World War II. The show features an intimidating setting and challenging questions. Four (and in later contests five or six) contestants face two rounds, one on a specialised subject of the contestant's choice, the other a general knowledge round.

Mastermind's theme music is "Approaching Menace" by the British composer Neil Richardson. The show was recorded, with original presenter Magnus Magnusson, on location at UK universities. Later, it was recorded in Manchester at studios such as New Broadcasting House and Granada Studios, before moving to dock10 studios in 2011. The show relocated to Belfast for the 2019–2020 series.
