Saleen Performance, Incorporated, commonly known as Saleen, is a manufacturer of high performance sports cars and high performance parts based in Irvine, California. The company was founded in 1983 by Steve Saleen, a former Formula Atlantic race car driver.

Saleen manufactures limited edition, high-performance vehicles. Saleen is an automotive Original Equipment Manufacturer (OEM) and the last American small car manufacturer bearing OEM status. Most of Saleen's vehicles are modified versions of existing mass produced sports cars such as the Ford Mustang. Saleen has produced over 8,000 modified Mustangs since its inception. It also produces modified versions of the Ford Focus and other Ford models.

Saleen's flagship car is the Saleen S7, introduced in 2000. The S7 is a mid-engine, high performance supercar that was first priced at just under US$400,000. The S7 won four different GT championships in 2001 and has broken records at the prestigious 24-Hour Le Mans race. The S7 is Saleen’s first production car not based on an existing design.

The parts and gear branch of the company markets car parts and accessories such as custom wheels, exhaust systems, brakes, and other high performance parts.

Saleen also operates a plant (Saleen Special Vehicles) in Troy, Michigan where it builds the Ford GT supercar.

As of mid-2005, Saleen discontinued manufacture of the "Nitrous-ready" S121 Saleen N2O Focus.
