Hugo Award for Best Professional Magazine

The Hugo Awards are given every year by the World Science Fiction Society for the best science fiction or fantasy works and achievements of the previous year. The award is named after Hugo Gernsback, the founder of the pioneering science fiction magazine Amazing Stories, and was once officially known as the Science Fiction Achievement Award. The award has been described as "a fine showcase for speculative fiction" and "the best known literary award for science fiction writing". The Hugo Award for Best Professional Magazine was given each year for professionally edited magazines related to science fiction or fantasy, published in English, and which has published four or more issues with at least one issue appearing in the previous calendar year. Awards are also given out for non-professional magazines in the fanzine category, and for semi-professional magazines in the semiprozine category.

The award was first presented in 1953, the first year any Hugo Award was given, and with the exception of 1954 was given annually through 1972 when it was retired in favor of the newly created professional editor category. For the 1957 awards, the category was split into American and British magazine categories, a distinction which was not repeated any other year. In addition to the regular Hugo awards, beginning in 1996 Retrospective Hugo Awards, or "Retro Hugos", have been available to be awarded for years 50, 75, or 100 years prior in which no awards were given. To date, Retro Hugo awards have been awarded for 1946, 1951, and 1954, but only for the professional editor category, not the professional magazine category that would have existed at the time.

Hugo Award nominees and winners are chosen by supporting or attending members of the annual World Science Fiction Convention (Worldcon) and the presentation evening constitutes its central event. The selection process is defined in the World Science Fiction Society Constitution as instant-runoff voting with five nominees, except in the case of a tie. These five works on the ballot are the five most-nominated by members that year, with no limit on the number of works that can be nominated. The 1953 through 1956 and 1958 awards did not include any recognition of runner-up magazines, but since 1959 all five candidates were recorded. Initial nominations are made by members in January through March, while voting on the ballot of five nominations is performed roughly in April through July, subject to change depending on when that year's Worldcon is held. Worldcons are generally held near the start of September, and are held in a different city around the world each year.

During the nineteen nomination years, twelve magazines run by fifteen editors were nominated. Of these, only five magazines run by eight editors won. Astounding Science-Fiction/Analog Science Fact & Fiction and The Magazine of Fantasy & Science Fiction each won eight times, out of eighteen and fifteen nominations, respectively. If won three of five nominations, New Worlds won one of its six nominations—though its win was in the 1957 "British Professional Magazine" category—and Galaxy Science Fiction won only one out of its fifteen nominations, for the first award in 1953. Of the magazines which never won, Amazing Stories was nominated the most at eight times, while the only other magazine to be nominated more than twice was Science Fantasy with three nominations. John W. Campbell, Jr. received both the most nominations and awards, as he edited Analog Science Fact & Fiction for all eighteen nominations and eight wins. Edward L. Ferman and Robert P. Mills both won four times, while Frederik Pohl won three. H. L. Gold received the second most number of nominations at twelve, while Cele Goldsmith received the most number of nominations without winning at ten for her work on two separate magazines; she was the only female editor to be nominated.
