The Opel Corsa is a supermini that has been produced and engineered by the German automaker Opel since 1982 and has also been sold under a variety of other brands (most notably Vauxhall, Chevrolet, and Holden), and also spawned various derivatives in different markets.

The front-wheel drive Opel Corsa was first launched in September 1982 to replace the Opel Kadett C City, and to fill the gap vacated as the Kadett grew in size and price. Built in Zaragoza, Spain, the first Corsas were three-door hatchback and two-door saloon models, with four-door and five-door versions arriving in 1984. In mainland Europe, the saloon versions were known as the "Corsa TR" until May 1985. The basic model was called just the Corsa, which was followed by the Corsa Luxus, Corsa Berlina and the sporty Corsa SR. Six years later, the Corsa received a facelift, which included a new front fascia and some other minor changes. The models were called LS, GL, GLS and GT.

The Corsa A was known in the UK market as the Vauxhall Nova, where it was launched in April 1983 following a seven-month long union dispute due to British workers being angry about the car not being built there. It effectively replaced the ageing Chevette, which was discontinued in January 1984.
