Holden Special Vehicles (HSV) is the officially designated performance vehicle partner of Australian automaker, Holden. Established in 1987 and based in Clayton, Victoria, the company modifies Holden models such as the standard-wheelbase Commodore, long-wheelbase Caprice and commercial Ute for domestic and export sale. Over the years, Holden Special Vehicles has also modified other non-Holden cars within the General Motors portfolio, in very low volumes.

Cars produced by Holden Special Vehicles have, in the main, been marketed under the HSV brand name. However, in the early years, some have retailed under the Holden name in Australia whereas most cars for export (other than in New Zealand and Singapore) have retailed under different names (namely, Vauxhall and Chevrolet Special Vehicles).
