New Writings in SF 15

New Writings in SF 15 is an anthology of science fiction short stories edited by John Carnell, the fifteenth volume in a series of thirty, of which he edited the first twenty-one. It was first published in hardcover by Dennis Dobson in 1969, followed by a paperback edition issued under the slightly variant title New Writings in SF-15 by Corgi the same year.

The book collects six novelettes and short stories by various science fiction authors, with a foreword by Carnell. The third and fourth stories were later reprinted in the American edition of New Writings in SF 9.
