Derren Brown (born 27 February 1971) is an English mentalist and illusionist. Since his television debut with Derren Brown: Mind Control in 2000, he has produced several other shows both for the stage, and for television in both series and specials. He has also written books for magicians as well as the general public.

Brown does not claim to possess any super-natural powers, indeed his acts are often designed to expose the methods of those who do, such as faith healers and mediums. He makes clear in his performances that all of his apparent abilities, which manifest on stage/screen as feats of memory, intuition, mind-reading and control of other objects/people, are achieved through a variety of psychological and sociological means, such as hypnosis, suggestion, cold reading, misdirection, and showmanship, and in many cases he will often give detailed explanations of his specific methods during or after the performance. In some performances he also uses his techniques to explore issues of personality such as fears and motivation.
