The 2009 Coca-Cola 600 was the twelfth stock car race of the 2009 NASCAR Sprint Cup Series and the fiftieth iteration of the event. It was held on May 25, 2009, at Lowe's Motor Speedway in Concord, North Carolina after being postponed on May 24 because of inclement weather. Scheduled for 400 laps on the 1.5-mile (2.4 km) quad-oval, the race was won by David Reutimann of Michael Waltrip Racing after being shortened to 227 laps because of poor weather conditions. Ryan Newman finished second ahead of Robby Gordon, Carl Edwards, and Brian Vickers, who completed the first five positions.
