Holden, formerly known as General Motors-Holden, was an Australian subsidiary company of General Motors. It was an Australian automobile manufacturer, importer, and exporter which 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.

Holden briefly owned assembly plants in New Zealand during the early 1990s. The plants had belonged to General Motors from 1926 until 1990 in an earlier and quite separate operation from GM's Holden operations in Australia. Holden's production became increasingly concentrated in South Australia and Victoria after the Second World War. However, Holden had factories in all the mainland states of Australia when GM took over in 1931, due to the combining of Holden and GM factories around the country under Holden management. In the postwar period, this decentralisation was slowly reduced and, by 1989, the consolidation of final assembly at Elizabeth, South Australia was largely completed, except for some operations that continued at Dandenong, Victoria until 1994. Engine manufacturing was consolidated at Fishermans Bend, Victoria, which was expanded to supply markets overseas.

Although Holden's involvement in exports had fluctuated from the 1950s, the declining sales of large sedan cars in Australia led the company to look to international markets to increase profitability. From 2010, Holden incurred losses due to the strong Australian dollar and reductions of government grants and subsidies. This led to the announcement, on 11 December 2013, that Holden would cease vehicle and engine production by the end of 2017. On 29 November 2016, engine production at the Fishermans Bend plant was shut down. On 20 October 2017, production of the last Holden designed Commodore ceased and the vehicle assembly plant at Elizabeth was shut down. On 17 February 2020, General Motors announced that the Holden marque would be retired by 2021. On 30 October 2020, the GM Australia Design Studio at Fishermans Bend was shut down. Holden has been replaced by GM Specialty Vehicles (GMSV), which imports the Chevrolet Silverado and the Chevrolet Corvette. The parts supplier known as the Holden Trade Club was renamed GM Trade Parts. An extensive Holden service network continues to help maintain the many Holdens that remain in operation in Australia.
