The Pontiac Fiero is a rear mid-engine, light sports car manufactured and marketed by Pontiac for model years 1984–1988.

Styled by George Milidrag and Hulki Aldikacti as an economical commuter car with modest performance aspirations, it was Pontiac's first two-seater since their 1926 to 1938 coupes, and the first rear mid-engine mass-produced car by any American manufacturer.

In addition to using 4- and 6-cylinder engines to help Pontiac meet America's 'CAFE' average fuel economy requirements, the Fiero's chassis and structure technology used non-load-bearing, composite body-panels, contributing to the car's light-weight and unique selling proposition. Pontiac engineers modified the design over its life to enhance its performance and reposition the two-seater closer to the implications of its sporty configuration.

The Fiero 2M4 (two-seat, mid-engine, four-cylinder) was on Car and Driver magazine's Ten Best list for 1984, and was the Official Pace Car of the Indianapolis 500 for 1984.

A total of 370,168 Fieros were manufactured over five years' production. After suffering criticisms related to its mild performance as well as reliability and safety issues, the Fiero was discontinued after annual sales fell steadily.
