The AMC Hornet is a compact automobile, manufactured and marketed by American Motors Corporation (AMC) and made from 1970 through 1977 — in two- and four-door sedan, station wagon, and hatchback coupe configurations. The Hornet replaced the compact Rambler American line, marking the end of the Rambler marque in the American and Canadian markets.

Hornets were marketed in foreign markets and were assembled under license agreements between AMC — for example, with Vehículos Automotores Mexicanos (VAM), Australian Motor Industries (AMI), and by Toyota S.A. Ltd. in South Africa.

The Hornet became important for the automaker in being a top seller during its production as well as a car platform serving the company in varying forms through the 1988 model year. Introduced in 1969, AMC earned a high rate return for its development investment for the Hornet. The platform became the basis for AMC's subcompact Gremlin, luxury compact Concord, liftback and sedan Spirit, and the innovative all-wheel drive AMC Eagle. It would also outlast the compact platforms from the competition, including the Chevrolet Nova, Ford Maverick, and Plymouth Valiant.

The AMC Hornet served as an experimental platform for alternative fuel and other automotive technologies. Hornets were campaigned in various motorsports events with some corporate support. A hatchback model also starred in an exceptional stunt jump in the 1974 James Bond film: The Man with the Golden Gun.
