SpaceGodzilla (スペースゴジラ Supēsugojira) is a crystalline Godzilla clone kaiju who first appeared in the 1994 Toho Godzilla film Godzilla vs. SpaceGodzilla.

SpaceGodzilla is Godzilla's penultimate foe in the Heisei series of films, as well as the only extraterrestrial creature introduced in that series. Boasting an array of psychic powers and energy attacks along with his ability to form and use crystals in various ways, SpaceGodzilla is a challenging opponent for other kaiju, like Godzilla.
