Shadowland was a science fiction fanzine published by Bill Shell and edited by Sam Martinez.
Published in Tulsa, Oklahoma, U.S.A., Shadowland was released in the 1950s. It was a Fantasy Amateur Press Association publication, but also available to non-members. It was a hectographed zine of around 52 pages. At least six issues were released between 1951 and 1954.
Contributions included "The Art Gallery" by Terry Carr (Innuendo), fiction by William Clyde (a hoax fan created by Martinez), and Don Womanski, and poetry by Bob Farnham (The Chigger Patch of Fandom), and by Orma McCormick (Starlanes).
In his review of Shadowland in Straight Up #5, Fred Robinson wrote, "A neat hectoed zine mainly intended for FAPA but available to non-members...I recommend it highly."
