New Writings in SF 11 is an anthology of science fiction short stories edited by John Carnell, the eleventh volume in a series of thirty, of which he edited the first twenty-one. It was first published in paperback by Corgi in 1967, followed by a hardcover edition by Dennis Dobson in 1968. This marked a reversal of the usual publication sequence, in which the Corgi paperback followed an initial hardcover from Dobson.
