Gamera: Super Monster (宇宙怪獣ガメラ, Uchū Kaijū Gamera, lit. 'Space Monster Gamera')^{[lower-alpha 1]} is a 1980 Japanese kaiju film directed by Noriaki Yuasa and produced by Daiei Film. It is the eighth film in the Gamera film series, following the release of Gamera vs. Zigra in 1971.

Gamera: Super Monster was distributed by New Daiei, and was released theatrically in Japan on 20 March 1980. It was followed by Gamera: Guardian of the Universe in 1995, which would mark the beginning of the franchise's Heisei period.

When the evil alien Zanon comes to enslave Earth, all hope seems lost. The Earth's resident superheroes, the Spacewomen, are powerless to stop him. They must enlist the help of a young boy who has a special connection with the giant turtle Gamera. The Friend of All Children then battles Gyaos (a huge vampire bat/pterosaur hybrid), Zigra (an alien shark), Viras (an alien squid), Jiger (a female giant dimetrodon-like monster), Guiron (a knife-headed alien monster) and finally Barugon (an enormous lizard whose tongue sprays a freeze-gas that can freeze things solid and whose back spines emit a powerful rainbow ray that can melt or dissolve any solid object). Gamera sacrifices his life in the end to destroy Zanon once and for all and to protect Earth one last time.

Gamera: Super Monster contains extensive stock footage of the entire Gamera film series, as well as Space Battleship Yamato and Galaxy Express 999.^[3] Almost all of the footage of Gamera is stock footage. The movie was made as an attempt to help Daiei get out of its turbulent financial situation.^[4]

The 1994 manga Giant Monster Gamera by Hurricane Ryu depicted that Gamera after the incident of Gamera: Super Monster was artificially resurrected and gained physical appearance and ability of the incarnation of the Heisei Trilogy.^[5]

Gamera: Super Monster was released theatrically in Japan on March 20, 1980, where it was distributed by New Daiei.^[1]
