Futuria Fantasia was an American science fiction fanzine created by Ray Bradbury in 1938, when he was 18 years old. Though only four issues of the fanzine were published, its list of contributors included Hannes Bok, Forrest J. Ackerman, Henry Kuttner, Damon Knight, and Robert A. Heinlein - which is known today as some of the world's most famous sci-fi authors.
