Peter Edward Cook (17 November 1937 – 9 January 1995) was a British satirist, writer and comedian. He is widely regarded as the leading figure in the British satire boom of the 1960s. He has been described by Stephen Fry as 'the funniest man who ever drew breath'.

Cook is very closely associated with the anti-establishment style of comedy that first emerged in Britain and the US in the late 1950s.

Cook was born at "Shearbridge", Middle Warberry Road, Torquay, Devon, the only son and eldest of the three children of Alexander Edward (Alec) Cook (d. 1984), a colonial civil servant, and his wife (Ethel Catherine) Margaret, née Mayo (d. 1994). He was educated at Radley College and later Pembroke College, Cambridge, where he read French and German. Cook meant to become a career diplomat, but unfortunately Britain "had run out of colonies", as he put it. It was at Pembroke that he performed and wrote comedy sketches as a member of the prestigious Cambridge Footlights Club, of which he became President in 1960.
