Geoffrey Bush (23 March 1920 – 24 February 1998) was a British composer, teacher and music scholar. Largely without formal training in composition, he produced a wide range of compositions across different genres, including many songs and works for choirs. He also edited and arranged the works of other composers. Most of his teaching was within the framework of the Extramural Departments at Oxford University and London University. He was a popular broadcaster on BBC music programmes, and the author of several books.
