The 1990 Annual World's Best SF

The 1990 Annual World's Best SF is an anthology of science fiction short stories edited by Donald A. Wollheim and Arthur W. Saha, the nineteenth volume in a series of nineteen. It was first published in paperback by DAW Books in July 1990, followed by a hardcover edition issued in August of the same year by the same publisher as a selection of the Science Fiction Book Club. For the hardcover edition the original cover art of Jim Burns was replaced by a new cover painting by Richard Powers.

The book collects twelve novelettes and short stories by various science fiction authors, with an introduction by Wollheim. The stories were previously published in 1989 in the magazines Amazing Science Fiction, Interzone, The Magazine of Fantasy & Science Fiction, and Isaac Asimov's Science Fiction Magazine, and the anthologies Zenith: The Best in New British Science Fiction and What Might Have Been? Vol II: Alternate Heroes.
