The 2008 Chevy Rock & Roll 400 was the twenty-sixth race of the 2008 NASCAR Sprint Cup season and served as the final "regular season" race before the 2008 Chase for the Sprint Cup, where the top twelve drivers were "locked into" the ten-race playoff.

The 400 lap (300 miles (480 km)) event was scheduled to have been held on Saturday night, September 6 at the 0.75 miles (1.21 km) Richmond International Raceway in Henrico County, Virginia, outside Richmond, the Commonwealth's capital city. However, Hurricane Hanna altered the plans and forced the race to be moved to the next day, September 7 at 1 PM US EDT. This was to have been the first race to be carried on ABC, however due to a prior commitment to carry both a WNBA game and an Indycar Series race in Chicago, ESPN carried the race. In place of the race that night, ABC aired the movie Catch Me If You Can. Radio coverage via MRN along with Sirius Satellite Radio commenced at 12 noon US EDT Sunday.

• As announced last week, 18-year-old sensation Joey Logano moved into the #20 Toyota at Joe Gibbs Racing after Tony Stewart leaves. He was to have attempted to qualify for this week's race driving the #02 ride. Tropical Storm Hanna had other ideas as qualifying was cancelled, and because he was outside the Top 35, he did not make the race. Logano will later try to run five races for Hall of Fame Racing in the #96 car later this season, and two more in the #02.
• NASCAR began a new drug testing policy within the next few weeks, and will now use random drug testing on all drivers, crews and other personnel as part of the new program. This puts the stock car sanctioning body with all the other major North American sports on random testing.
• David Stremme, who lost his ride to Dario Franchitti, became the new driver of the #12 Penske Racing Dodge in 2009. Stremme had been driving in the Nationwide Series and was a test driver for PR this year.

David Reutimann dominated the race and led 104 laps, but a braking problem cut his hopes short. It was Jimmie Johnson who took over and won the race by holding off a determined Tony Stewart. David Ragan's chances of making the chase were all but finished when he was involved in an incident with teammate Matt Kenseth. Jimmie Johnson held off Tony Stewart and win the first daytime fall race at Richmond since 1990.

It was the first Sprint Cup race since the 2007 Sylvania 300 where all 43 cars started finished the race, with no retirements.

Drivers in green made Chase for Sprint Cup.
