Holden Australia is an Australian car manufacturer, originally independent but now a subsidiary of General Motors.

Holden began as Holden's Motor Body Builders Ltd., a coachbuilder that made bodies to suit a number of chassis imported from different manufacturers, but particularly Chevrolet. It was purchased by General Motors in 1931 and became General Motors–Holden's Ltd. In 1998, it was renamed Holden Ltd and in May 2005, it became known as GM Holden Ltd.

Although its Opel-sourced models have been relatively successful, Holden has now looked to Daewoo in South Korea for replacements. Holden has already established close research and design links with Daewoo, with which it provides the large Statesman model. The Holden Barina will be based on the Daewoo Kalos, and the entry-level Astra Classic will be replaced by the Holden Viva, based on the Daewoo Lacetti. Due to tariffs and exchange rates, various Vectra models are more expensive than the larger Commodore in Australia and New Zealand, and the European model is likely to be replaced by a version of the new Daewoo Magnus in 2006.

The Holden Commodore is as popular in New Zealand as it is in Australia, often being used as a police car. It is also sold in South Africa, Thailand, and parts of the Middle East badged as a Chevrolet Lumina, and in Brazil as the Chevrolet Omega. Holden also exports its Statesman sedan to the Middle East as the Chevrolet Caprice, to South Korea as the Daewoo Statesman, and China as the Buick Royaum. Between 1968 and 1974, GMH sold a two-door variant of their full-size Holden sedan as the Monaro, a revived Monaro, based on the previous model Commodore, has attracted wide attention and a large waiting list after it was put into production. The revived Monaro was released in the Australian market in October 2001. Starting with the 2004 model year, the Monaro has been exported to the United States, rebadged as the Pontiac GTO, and the Middle East, rebadged as the Chevrolet Lumina Coupe. It is sold in limited numbers in the UK as the Vauxhall Monaro.

Holden Special Vehicles (HSV) is a wholly-owned subsidiary of Holden selling extensively modified, high-performance Commodore variants (including the Monaro and the Statesman). . Holdens have been a staple of domestic touring car racing since the 1960s, and the quasi-factory Holden Racing Team has been dominant in V8 Supercar racing.
