William Turner Walton (March 29, 1902 - March 8, 1983) was a British conductor and composer in the post-Romantic style. His major works are Façade (1922), the Viola Concerto (1929), the large-scale cantata Belshazzar's Feast (1931), the Symphony #1 (1935), the Crown Imperial coronation march (1937), the Violin Concerto (1939), String Quartet #2 (1946), the Cello Concerto (1956), Symphony #2 (1960), and the Variations on a Theme by Hindemith (1963).

As an alternative to military service during World War II, Walton was granted leave to compose music for the movies, such as the propagandistic The First of the Few (1942). His best work in cinema came with his scores for the Laurence Olivier films Henry V (1944), Hamlet (1948), and Richard III (1955).
