The winners were:<ref name=hugo_57/>

* Best American Professional Magazine: ''Astounding Science Fiction'', edited by John W. Campbell, Jr. * Best British Professional Magazine: ''New Worlds'', edited by John Carnell * Best Fanzine: ''Science Fiction Times'', edited by James V. Taurasi, Sr., Ray Van Houten, and Frank R. Prieto, Jr.

Because the 1957 International Fantasy Award was being given out in London at the same time, Loncon I chose not to compete with this similar literary award, which was given to J.R.R. Tolkien's ''The Lord of the Rings''. As a result, only the three Hugo Awards for Best Professional Magazine and Best Fanzine were given out at the 1957 Worldcon. Both the International Fantasy Award and the Hugo Award shared the very same Chesley Bonestell-influenced finned rocketship design that year, the only time this has happened.
