Fantasias was a science fiction fanzine by David English published in New York, U.S.A.
At least seven issues of this mimeographed fanzine appeared in the 1950s, with issue 1 released in October 1951.
Art work was by Orville W. Mosher and David English.
Issue 2 included writing by J.T. Oliver (Worlds Apart), with the story "The Trainer"; Bobby Pope (Fanatic Fanzine), with the article "How to build a Rocketship that actually blasts off"; and Bill Venable (Aleph-Null), with "The Hardest Job In Fandome".
Issue 8, the last issue, appeared in July 1953.
Fantasias was a member of "Fanvariety Enterprises", an affiliation of fan publishers put together by Max Keasler and Bill Venable. It included such publications as Max Keasler's Opus, Bill Venable's The Pendulum, Norman Browne's Vanations, Harlan Ellison's Science Fantasy Bulletin, Bob Farnham and Nan Gerding's The Chigger Patch of Fandom, Norbert Hirschhorn's Tyrann, Ian MacAuley's Cosmag, John Magnum's SF, Joel Nydahl's Vega, and Starlanes by Nan Gerding and Orma McCormick.
David English's drawings were well regarded by fanzine editors. In June 1958, Larry Stark published A David English Sketchbook, a collection of English's work. As well, his writing appeared in publications such as Magazine of Horror and Strange Tales.
