Science Fiction Adventures was a British digest-size science fiction magazine, published from 1958 to 1963 by Nova Publications as a companion to New Worlds and Science Fantasy. It was edited by John Carnell. Science Fiction Adventures began as a reprint of the American magazine of the same name, Science Fiction Adventures, but after only three issues the American version ceased publication. Instead of closing down the British version, which had growing circulation, Nova decided to continue publishing it with new material. The fifth issue was the last which contained stories reprinted from the American magazine, though Carnell did occasionally reprint stories thereafter from other sources.
