Out of Space and Time is a collection of fantasy, horror and science fiction short stories by American writer Clark Ashton Smith.

A British hardcover appeared from Neville Spearman in 1971, with a two-volume paperback reprint following from Panther Books in 1974.

Smith had wanted to call the collection "The End of the Story and Other Stories", but acceded to Derleth's suggestion, an allusion to Edgar Allan Poe's "Dream-Land".

[2] Out of Space and Time contains the following tales: Writing in Unknown Worlds, Anthony Boucher described the collection as "four hundred pages of magnificent reading", praising Smith as "a poet and a craftsman [who] has produced by far the best work in the Lovecraft tradition".

[3] New York Times reviewer Louise Maunsell Field noted that while most of Smith's stories were "overelaborated and far too wordy", the author had "an active, fertile imagination", concluding that the collection would please "[r]eaders who delight in fantasy and witchcraft".
