Fan Slants was a science fiction fanzine co-edited by Mel Brown and Mike Fern in the U.S.A.
Three issues of Fan Slants appeared between 1943 and 1944.
All three issues have covers by Ronald Clyne, with interior art work by him as well. According to a later account by Francis Laney, editor Mel Brown had to do some wheeling and dealing with LASF member Walter Daugherty, who had managed to obtain all of Clyne's work for fanzines, to be able to use the cover Ronald Clyne had done especially for his first issue of Fan Slants.
Contributors of writing included Forrest J. Ackerman (Voice of the Imagi-Nation), Phil Bronson (The Fantasite, Scienti-Comics), Walter J. Daugherty, Charles Dye, Paul Freehafer (Polaris), William Hamling, Arthur Joquel (FMZ Digest, Sun Trails), James Kepner, Francis T. Laney (The Acolyte), Walt Liebscher (Chanticleer), Emile Petaja, Duane Rimel, Bob Tucker (Le Zombie), Gus Willmorth, Donald Wollheim (The Phantagraph), and T. Bruce Yerke (The Damn Thing).
