The Ballantine Adult Fantasy series was an imprint of American publisher Ballantine Books. Launched in 1969 (presumably in response to the growing popularity of Tolkien's works), the series reissued a number of works of fantasy literature which were out of print or dispersed in back issues of pulp magazines (or otherwise not easily available in the United States), in cheap paperback form—including works by authors such as James Branch Cabell, Lord Dunsany, Ernest Bramah, Hope Mirrlees, and William Morris. The series lasted until 1974.
