Godzilla vs. Mechagodzilla II (ゴジラvsメカゴジラ, Gojira tai Mekagojira, released in Japan as Godzilla vs. Mechagodzilla), is a 1993 Japanese kaiju film directed by Takao Okawara, with special effects by Kōichi Kawakita. Distributed by Toho and produced under their subsidiary Toho Pictures, it is the 20th film in the Godzilla franchise, as well as the fifth film to be released during the franchise's Heisei era. The film features the fictional monster character Godzilla, along with Baby Godzilla, Rodan and the mecha character Mechagodzilla. Despite its English title, the film is not a sequel to the 1974 film Godzilla vs. Mechagodzilla.

Godzilla vs. Mechagodzilla II was released theatrically in Japan on December 11, 1993, to generally positive reviews from critics. The film was a commercial success, generating a combined $194,000,000 (equivalent to $422,000,000 in 2024) from the box office, book sales and merchandise sales by 1994. It was the first Japanese film to use Dolby Digital sound format. It was released directly to pay-per-view satellite television in the United States in 1998 by Sony Pictures Television. The film was promoted as the last film in the franchise's Heisei series, and was also promoted by a children's television program called Adventure! Godzilland 2. Although Godzilla vs. Mechagodzilla II was not the final entry in the Heisei series, as it was followed by Godzilla vs. SpaceGodzilla in 1994, Toho producers initially wished to avoid competing with TriStar's then-upcoming Godzilla reboot.
