The AMC Hornet was an compact automobile made by American Motors Corporation (AMC) starting in the 1970 model year and continuing through most of the following decade.

The name Hornet had first been applied to full-sized Hudson Motors products in the early 1950s. AMC - the resulting corporation formed by the merger of Nash Motors and Hudson - produced the last Hudson Hornet in 1957, and the name had been dormant since then with AMC retaining full rights use.

The AMC Hornet replaced the replaced the Rambler American, and thus ended the Rambler marque as a make of automobile, in U.S. and Canadian markets. The Hornet was offered in door sedans, two-door hatchback and four-door "Sportback" form, which resembled a hatch-back station wagon in form and function, but was limited in its cargo capacity and ease of loading due to a high "lift-up" thresehold.

The two-door Hornet also served as the basis for the two-door AMC Gremlin, which used the front half body stamping of the Hornet two-door, with a truncated rear section with a window hatchback configuration.

The Hornet was the basis for most of AMC's output for 18 years. After minor redesign it was renamed the Concord and a four-wheel-drive version was named the Eagle.
