Fantasias was a science fiction fanzine by David English published in New York, U.S.A.
At least five issues of this mimeographed fanzine appeared in the 1950s.
Art work was by Orville W. Mosher and David English.
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 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, 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.
