The Best Science Fiction of the Year #13 is an anthology of science fiction short stories edited by Terry Carr, the thirteenth volume in a series of sixteen. It was first published in paperback by Baen Books in July 1984, and in hardcover and trade paperback by Gollancz in December of the same year.

The book collects ten novellas, novelettes and short stories by various science fiction authors, with an introduction, notes and concluding essays by Carr and Charles N. Brown. With one exception, the stories were originally published in 1983 in the magazines Analog Science Fiction/Science Fact, The Magazine of Fantasy & Science Fiction, Isaac Asimov's Science Fiction Magazine, Omni, and Interzone, and the anthology Universe 13. The exception is "Scenes from the Country of the Blind," which originally appeared in the British anthology A Book of Contemporary Nightmares in 1977. Its inclusion in Carr's best of the year anthology for 1983 stemmed from its first American publication that year in Isaac Asimov's Science Fiction Magazine.
