The Indy Grand Prix of Sonoma is an IndyCar Series race held at Infineon Raceway in Sonoma, California. The USAC Championship Car circuit raced at the circuit in 1970. In 2005, American open wheel racing returned to the circuit with an IndyCar Series event. The 2006 event saw rookie Marco Andretti win his first career race. It marked the record youngest winner (19 years, 5 months, 14 days) of a major open-wheel racing event at the time.

The IndyCar Series race utilizes a modified 2.2-mile (3.5 km) version of the road course, the same used by AMA Superbike. The circuit includes the carousel, making it longer than the NASCAR layout, but shorter than the full 2.52-mile (4.06 km) course. This course uses turn 7a of the NASCAR course, but skips the hairpin prior to the front straight.
