Peter Edward Cook (17 November 1937 – 9 January 1995) was an English actor, satirist, writer and comedian. Cook is widely regarded as the leading light of the British satire boom of the 1960s. He was closely associated with the anti-establishment comedy that emerged in the United Kingdom and United States in the late 1950s.

Called "the father of modern satire" by The Guardian, in 2005, Cook was ranked number one in the Comedians' Comedian, a poll of over 300 comics, comedy writers, producers, and directors throughout the English-speaking world.
