Sacha Noam Baron Cohen (born 13 October 1971) is an English actor, comedian, and writer. A graduate of Christ's College, Cambridge (a constituent college of the University of Cambridge), Baron Cohen is most widely known for creating and playing four fictional characters: Ali G, Borat Sagdiyev, Brüno Gehard and Admiral General Aladeen. In most of his routines, Baron Cohen's characters interact with unsuspecting people who do not realise they are being set up for comic situations and self-revealing ridicule.

Baron Cohen was named Best Newcomer at the 1999 British Comedy Awards for The 11 O'Clock Show, and since then, his work has been further recognised with two BAFTA Awards for Da Ali G Show, several Emmy nominations, a nomination for an Academy Award for Writing Adapted Screenplay, and a Golden Globe for Best Actor for his work in the feature film Borat. After the release of Borat, Baron Cohen stated that because the public had become too familiar with the characters, he would retire Borat and Ali G. Similarly, after the release of Brüno, Baron Cohen stated he would also retire the title character. At the 2012 British Comedy Awards, he received the Outstanding Achievement Award, accepting the award while reprising his Ali G character. In 2013, he received the BAFTA Charlie Chaplin Britannia Award for Excellence in Comedy.
