Automobiles Cousy was a French automobile manufacturer established in 1955, located in Castillon-la-Bataille, Gironde. The company specialized in producing lightweight sports cars that were designed for both circuit racing and road use.

The flagship model, known simply as the Cousy, featured a distinctive plastic body that contributed to its low weight of just 360 kilograms. This lightweight construction was complemented by a tubular chassis, which enhanced the car's performance and handling. The Cousy offered a choice of engines, including a rear-mounted 500cc BMW engine or a Panhard Dyna engine, allowing for a degree of customization based on the driver's preferences.

Despite its innovative design and engineering, Automobiles Cousy had a limited production run and eventually ceased operations. The brand remains a notable example of mid-20th century French automotive engineering, reflecting the era's interest in lightweight sports cars.
