Holden, officially GM Holden Ltd, is an Australian automaker based in Port Melbourne, Victoria. The company was originally independent but since 1931 has been a subsidiary of General Motors (GM). Holden has taken charge of vehicle operations for General Motors in Australasia and, on behalf of GM, holds partial ownership of GM Daewoo in South Korea. Over the years, Holden has offered a broad range of locally produced vehicles, supplemented by various imported GM models. In the past, Holden has offered rebadged Nissan and Toyota models in sharing arrangements.

Holden car bodies are manufactured at Elizabeth, South Australia, and engines are produced at Port Melbourne, Victoria (Fishermens Bend). Historically, production or assembly plants were operated in all mainland states of Australia: Acacia Ridge, Queensland, Dandenong, Victoria, Mosman Park, Western Australia, Pagewood, New South Wales, and Woodville, South Australia (body production only). Until 1990, Holden New Zealand also operated a plant based in Petone. The consolidation of car production at Elizabeth, South Australia, was completed in 1988, but some assembly operations continued at Dandenong until the mid-1990s.

Although Holden's involvement in exports has fluctuated since the 1950s, the declining sales of large cars in Australia has led the company to look to international markets to increase profitability; in 2006, exports alone accounted for almost AU$1.3 billion in earnings.
