Douglas Gamley (24 September 1924, Melbourne – 5 February 1998) was an Australian film composer, who worked on British and American films.
He was particularly influenced by Modest Mussorgsky, creating a full orchestral version of his Pictures at an Exhibition, and adapting his Night on Bald Mountain for his score for Asylum (1972). He also adapted Faure's Pavane for The Monster Club.
He also did many vocal arrangements for Dame Joan Sutherland and Dame Kiri Te Kanawa, both for performing and recordings. He was associated for many years with the Australian Pops Orchestra as conductor and arranger.
