Camilla M. Gray, also known as Camilla Gray-Prokofieva, (1936 – 17 December 1971) was a British art historian whose book, The Great Experiment: Russian Art 1863–1922, broke new ground in promoting this branch of modernism. Gray organised several exhibitions in London on the relevant artists such as Kazimir Malevich, Mikhail Larionov, and Natalia Goncharova. She married Oleg Prokofiev, son of the composer Sergei Prokofiev.
