Galaxy Express 999 (銀河鉄道999スリーナイン, Ginga Tetsudō Surī Nain) is a Japanese manga series. It is written and illustrated by Leiji Matsumoto, later adapted into a number of anime films and television series. It is set in a spacefaring, high-tech future in which humans have learned how to transfer their minds and emotions with perfect fidelity into mechanical bodies, thus achieving practical immortality.

The manga won the Shogakukan Manga Award for shōnen in 1978. The anime series won the Animage Anime Grand Prix prize in 1981.

Matsumoto was inspired to create Galaxy Express 999 by the idea of a steam train running through the stars in the novel Night on the Galactic Railroad by Kenji Miyazawa.
