Galaxy Express 999 (銀河鉄道999, Ginga Tetsudō Surī Nain) is a song by Japanese rock band Godiego, released as their 11th single.

Like many Godiego songs, it is both in Japanese and English; the English lyrics were written by Yōko Narahashi and the Japanese lyrics were written by Keisuke Yamakawa.

To differentiate it from the theme song of the anime which has the same name in Japanese, it is often referred to by its English title which is stylized as "THE GALAXY EXPRESS 999".

The Exile cover was digitally commercially successful, being certified by the RIAJ as being downloaded more than one million times as a ringtone,[1] and more than 500,000 times as a full-length cellphone download.

[2] The Sanyo Shinkansen uses two adapted covers from the song at JR West stations as the Shinkansen departure melody for trains running east (towards Osaka) and west (towards Hakata).
