George William John Benjamin, CBE (born 31 January 1960) is a British composer of classical music. He is also a conductor, pianist and teacher.
Benjamin's oeuvre has been described as exhibiting "consummate craftsmanship" coloured by "a love of rich and unusually coloured sonorities".
Benjamin taught composition at the Royal College of Music, London, for sixteen years, where he became the first Prince Consort Professor of Composition before he succeeded Sir Harrison Birtwistle as Henry Purcell Professor of Composition at King's College London in January 2001. Benjamin has been a teacher and mentor to such younger composers as Luke Bedford and Dai Fujikura.
