Orion was a science fiction fanzine published in the 1950's in the UK.
The first 20 issues of Orion were published by Paul Enever, from December 1953 till 1958.
He then gave over the editorship to Ella Parker, who continued to publish it under the same name for several more years. In her first year of editorship she entered the Skyrack Readers Fan Poll as the third favourite fanzine in Britain.
Contributors during this time included John Berry, Sid Birchby, Keith Elliot, Paul Enever, Rory Faulkner, Jim Groves, Sandra Hall, Fred Hunter, Terry Jeeves, George Locke (Smoke), Archie Mercer, Len Moffatt, Joe Patrizio, Alan Rispin, Harry Warner, Jr. (Horizons), Bobby Wild, and Andy Young. Ken Bulmer published regular installments of his "TAFF Tales" (TransAtlantic Fan Fund Tales). Arthur Thomson regularly supplied the highly regarded covers and illustrations, as well as reviewing fanzines.
Orion won the Skyrack Readers Fan Poll for Best British Fanzine for the year 1960. In 1961, it came in second, beaten by another of Parker's publications, The ATom Anthology.
Ella Parker ceased publication of Orion in 1962, after 29 issues had been published. The same year she again won the Skyrack Readers Fan Poll, this time for Fan Personality of the Year.
