Sir George Henry Martin CBE (3 January 1926) is a British record producer, arranger and composer. He is sometimes referred to as "the Fifth Beatle"—a title that he owes to his work as producer of all but one of The Beatles' original records, as well as playing piano on some of The Beatles tracks—and is considered one of the greatest record producers of all time.

In 1969 he established the Associated Independent Recording (AIR) Studios. Although officially retired, he is still the chairman of the AIR board.

In recognition of his services to the music industry and popular culture, he was made a Knight Bachelor in 1996. He is the father of producer Giles Martin, and actor Gregory Paul Martin.
