After 12,000 Years is a science fiction novel by American writer Stanton A. Coblentz. It was first published in book form in 1950 by Fantasy Publishing Company, Inc. (FPCI) in an edition of 1,000 copies, of which 750 were hardback. Lloyd Arthur Eshbach regarded this as one of the stronger titles published by FPCI. Considered one of the author's most bizarre and most interesting futuristic fantasies, the novel originally appeared in the Spring 1929 issue of the magazine Amazing Stories Quarterly. The novel was abridged for the FPCI publication. E. F. Bleiler considered the unabridged version to be superior.
