Hugo Award for Best Fanzine

The Hugo Award for Best Fanzine is given each year for non professionally edited magazines, or "fanzines", related to science fiction or fantasy which has published four or more issues with at least one issue appearing in the previous calendar year. Awards were also once given out for professional magazines in the professional magazine category, and since 1984 have been awarded for semi-professional magazines in the semiprozine category; several magazines that were finalist in or won the fanzine category have gone on to be finalists in or win the semiprozine category since it was established.
