Eric Arnold Roberts Ennion (1900–1981) was a British artist, writer, illustrator, and radio presenter,^[1] specialising in birds and other natural history subjects.

Following education at Epsom College^[1] and Caius College, Cambridge^[1] and training at St Mary's Hospital,^[1] he worked for twenty years as a general practitioner at a large country practice in Burwell on the fen borders of Cambridge,^[1] where he had spent his childhood. A career change in 1945 saw him become warden at the Field Studies Council's Flatford Mill Field Centre,^[1] and from 1950, founder and director of the Monks' House Bird Observatory at Seahouses, Northumberland, which he wrote about in The House on the Shore.^[1] Ennion was a founder member and Honorary Vice President of the Society of Wildlife Artists.

His son, Hugh, is also an accomplished artist.
