The Opel Tigra (Also known as the Tigra TwinTop from 2004-2009) name has been applied to two different cars engineered and produced by the German automaker Opel, both based on different iterations of the Corsa supermini, the first built in Spain, the second in France. The first Tigra was a small 2+2 coupé, produced from 1994 to 2000. The later hard-topped convertible roadster model was introduced in 2004. The Tigra was sold in the UK as the Vauxhall Tigra, in Australia as the Holden Tigra, and was sold in Brazil, Argentina and Mexico as the Chevrolet Tigra.

The first Tigra was based on the coupe concept car of the same name that was shown at the 1993 Frankfurt Motor Show, alongside an open-top Tigra Roadster concept and the Scamp off-roader/pick-up. The Tigra built on the platform of the second generation Opel Corsa. The production vehicle was introduced in early 1994, and was built at Opel's Zaragoza plant in Spain.

The Tigra shared no body panels with the Corsa on which it was based, and the interior layout was different, with a 2+2 seating arrangement. Due to the coupe styling and compact dimensions of the car, rear seat space was limited.
