This is a list of the works that have won both the Hugo Award and the Nebula Award, given annually to works of science fiction or fantasy literature. The Hugo Awards are voted on by science-fiction fans at the World Science Fiction Convention (Worldcon); the Nebula Awards—given by the Science Fiction and Fantasy Writers of America (SFWA)—began in 1966, making that the first year joint winners were possible.
The categories are defined by number of words, as follows:
- Novel: >39,999 words
- Novella: 17,500 - 39,999 words
- Novelette: 7,500 - 17,499 words
- Short story: <7,500 words
Hugo awards are denoted by the year the award is presented, while Nebulas are denoted by the year of publication. This means that the years of the awards will be different for any given work. Prior to 2009 there was an additional complication with works being eligible for the Nebula for more than a single calendar year. For recent awards, only one date is shown below.
