George Robert Crotch (1842–1874) was a British entomologist.

Born in Cambridge, England, Crotch became interested in insects, especially Coleoptera, whilst an undergraduate at Cambridge University. He worked at the University Library, Cambridge. He collected insects in Europe and in the autumn of 1872, he left England on an entomological tour of the world, initially arriving at Philadelphia. In the spring of 1873 he arrived in California, where he collected insects until early July, when he traveled to British Columbia. In 1873 he accepted a position as assistant from Louis Agassiz at the Harvard Museum of Comparative Zoology with Hermann August Hagen. He made collections of Coleoptera and Lepidoptera during 1873 in California, Oregon, and Vancouver Island, as well as various areas of south-central British Columbia. He died of tuberculosis in 1874 at age 32.

Crotch was the author of a number of books, including Checklist of the Coleoptera of America (1873) and A revision of the Coleopterous family Coccinellidae (1874). His Coleoptera collection from the Azores is in the British Museum, London while the European Coleoptera, Erotylidae and Coccinellidae were left to the Cambridge University Museum of Zoology.

He was an authority on the Coccinellidae (Ladybird beetles) and Erotylidae of the world.
