Holden, formerly known as General Motors-Holden, was an Australian subsidiary company of General Motors. It was an Australian 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.

Holden's primary products were its own models developed in-house, such as the Holden Commodore, Holden Caprice, and the Holden Ute. However, Holden had also offered badge-engineered models under sharing arrangements with Chevrolet, Isuzu, Nissan, Opel, Suzuki, Toyota, and Vauxhall Motors. The vehicle lineup had included models from GM Korea, GM Thailand, GM North America. Holden had also distributed GM's German Opel marque in Australia in 2012 and 2013.

Holden was founded in 1856 as a saddlery manufacturer in South Australia. In 1908, it moved into the automotive field. It became a subsidiary of the United States–based General Motors (GM) in 1931, when the company was renamed General Motors-Holden's Ltd. It was renamed Holden Ltd in 1998 and adopted the name GM Holden Ltd in 2005.
