The Holden Gemini is a compact car that was produced by Holden and sold in Australasia from 1975 to 1987. It was based on the Japanese Isuzu Gemini, one of the many models based on the GM T-car platform.

Holden, formerly known as General Motors-Holden, was an Australian subsidiary company of General Motors. Founded in Adelaide, South Australia, it was an automobile manufacturer, importer, and exporter that sold cars under its own marque in Australia. In its last three years, it switched entirely to importing cars. It was headquartered in Port Melbourne, with major industrial operations in the states of South Australia and Victoria. The 164-year-old company ceased trading at the end of 2020.
