John Alexander Fuller Maitland (7 April 1856 – 30 March 1936) was an influential British music critic and scholar from the 1880s to the 1920s. He encouraged the rediscovery of English music of the 16th and 17th centuries, particularly Henry Purcell's music and English virginal music. He also propounded the notion of an English Musical Renaissance in the second half of the 19th century, particularly praising Charles Villiers Stanford and Hubert Parry.
Fuller Maitland was criticised for his failure to acknowledge the talents of the English composers Arthur Sullivan, Edward Elgar and Frederick Delius, and later it was shown that he had falsified the facts in a critique of Sullivan. He was also slow to recognise the worth of contemporary composers from mainland Europe such as Claude Debussy and Richard Strauss.
