These are a series of incomplete lists of fictional astronauts appearing in various media, including books, film, television shows (live or animated), radio shows, records, and comic books.
To be included in these lists, a fictional astronaut must be modeled upon actual astronauts of real-world space programs, as they have actually existed since the beginning of the Space Age, or were envisioned in the years leading up to the Space Age. Criteria include:
- A fictional astronaut must be human (not an alien, robot, or animal).
- A fictional astronaut must be on a flight originating from the Earth; space travellers engaging in casual voyages between other planets (as in Star Wars or Battlestar Galactica) are not eligible.
- A fictional astronaut must be presented as living in the period of the early exploration of space, i.e. from the beginning of the Space Age to the present, and for a few decades into the future; currently, in the period of about 1960–2060.
- A fictional astronaut is preferably part of a real space program, like NASA or the Soviet/Russian space program, or fictional knockoffs of the same (e.g. ANSA, IASA).
- A fictional astronaut preferably uses space travel technology within the realm of the possible. Preference should be given to astronauts depicted using real technology (e.g. Apollo, Soyuz, Space Shuttle) or close fictional knockoffs of the same.
