SF Masterworks

S.F. Masterworks is a series of science fiction novel reprints published by UK-based company Orion Publishing Group, a subsidiary of Hachette UK. The series is intended for the UK and Australian markets, but many editions are distributed to the United States and Canada by Hachette Book Group. As of December 2025, 199 unique titles and approximately 308 volumes, including hardcover, revised, or reprinted editions, have been published. Superseding the earlier series Gollancz Classic SF (1986–1987) and VGSF Classics (1988–1990), the SF Masterworks series began publication in 1999. Developed to feature important and out of print science fiction novels, the selections were described by science fiction author Iain M. Banks as "amazing" and "genuinely the best novels from sixty years of SF". Many of the selections had been out of print in the United Kingdom for several years. Its companion series include Fantasy Masterworks and Gateway Essentials.
