Crown Imperial is an orchestral march by the English composer William Walton. It was first performed at the coronation of King George VI in 1937, and substantially revised in 1963. Walton composed the march originally for performance at the coronation of King Edward VIII, which was scheduled for 12 May 1937. However, Edward abdicated in 1936. The coronation was held on the scheduled day, with Edward's brother George VI being crowned instead.
