Peter Malcolm Galton (born 14 March 1942 in London) is a British vertebrate paleontologist who has to date written or co-written about 190 papers in scientific journals or chapters in paleontology textbooks, especially on ornithischian and prosauropod dinosaurs.

With Robert Bakker in a joint article published in Nature in 1974, he argued that dinosaurs constitute a natural monophyletic group, in contrast to the prevailing view that considered them polyphyletic and consisting of two different unrelated orders, thus initiating a revolution in dinosaur studies and contributing to the revival of the popularity of dinosaurs in the field of paleontology.
