Alec Frederick Fraser-Brunner (born 6 April 1906—died 17 Sept 1986) was a British ichthyologist. His career included work with the Colonial Office, the Food and Agriculture Organization, and as the curator of the Van Kleef Aquarium in Singapore and the aquarium at Edinburgh Zoo. Amongst his written works is Cussons Book of Tropical Fishes, published as result of Manchester industrialist Alexander Tom Cussons' interest in tropical fish. Cussons had a keen interest in orchids.
