The 2008 Honda Grand Prix of St. Petersburg was the second round of the 2008 IndyCar Series season and took place on April 6, 2008 at the 1.8-mile (2.9 km) temporary street and airport circuit on the streets of St. Petersburg, Florida. The race was a time-limited race due to rain, with the race falling some seventeen laps short of full race distance. The race was won by Graham Rahal on his IndyCar Series debut, having missed the first round at Homestead-Miami Speedway, due to a lack of spare parts for his #06 Newman/Haas/Lanigan Racing machine.
