10 Story Fantasy (occasionally referred to as Ten Story Fantasy) was a science fiction and fantasy pulp magazine which was launched in 1951. The market for pulp magazines was already declining by that time, and the magazine only lasted a single issue. The stories were of generally good quality, and included work by many well-known writers, such as John Wyndham, A.E. van Vogt and Fritz Leiber. The most famous story it published was Arthur C. Clarke's "Sentinel from Eternity", which later became part of the basis of the movie 2001: A Space Odyssey.
