Arthur Erskine Ellis (1 October 1902 – 28 February 1983), often known as A.E. Ellis, was a British scientist, biologist and naturalist. Ellis is best known for his large number of malacological publications, including some which became essential texts on the subject of British non-marine malacology. To a lesser extent, Ellis published papers about other land invertebrates and various aspects of the fauna and flora of Britain. In addition Ellis had five ghost stories published. Ellis was also a plant collector. From 1919 to 1961 he contributed specimens of spermatophytes to a number of different herbariums in Britain. Stella Turk, the British naturalist said about Ellis, "It is difficult to categorise people. Should one even try? We are all multiple in a singular way!"; she also commented, "As might have been expected, he wrote his own obituary in which he gives a broad outline of his life and very lengthy bibliography", (J. Conch. 31 1983). Taxa named in his honour Two taxa were named in Ellis' honour: Limicolariopsis ellisi Crowley & Pain, 1964 (Rev. Zool.
