The Pagani Zonda GR is a high-performance racing version of the Pagani Zonda supercar and is manufactured by Italian company called Pagani.

Development of the Zonda GR started in December, 2002. At this stage the Zonda was nearly four years old, but had yet to be entered in major motorsports. Tom Weickardt, owner of American Viperacing, Toine Hezemans, owner of Carsport Holland, and Paul Kumpen, owner of GLPK, created a new company, Carsport Zonda, to build a racing version. They secured exclusive rights to develop, build and sell competition Zondas from Horacio Pagani, and the first GR was completed at Carsport's facility in Modena within months. The Zonda GR is based on the Zonda C12 S. It was built on the same carbon fiber chassis, with tube frames in front and back. The bodywork was modified to include front and rear diffusers and louvers for improved aerodynamics. The car was 2 m (6.6 ft) wide, in accordance with the regulations of the FIA and ACO. The car's weight was reduced to 1100 kg (2425 lb), and a new suspension was designed. New wheels and brakes were also specified. The engine was equipped with an enlarged radiator, and the engine and gearbox also have new oil coolers.

The performance of the Zonda GR is well beyond that of the stock car. The car sprints from 0 to 60 mph (97 km/h) in 3.3 seconds and the engine produces around 600 PS (around 440 kW) at 5800 rpm and 580 ft·lbf (786 N·m) of torque at 4300 rpm with a redline increased to 7500 rpm. The added power and improved aerodynamics allow the car to hit 215 mph (346 km/h).
