List of joint winners of the Hugo and Nebula awards

This is a list of the works that have won both the Hugo Award and the Nebula Award, awarded annually to works of science fiction literature. The Hugo Awards are voted on by science-fiction fans (at the World Science Fiction Convention); the Nebula Awards are given by the Science Fiction and Fantasy Writers of America (SFWA). The Nebula Awards began in 1966, making that the first year joint winners were possible.
