The 2010 Food City 500 was held on March 21, 2010 at Bristol Motor Speedway in Bristol, Tennessee as the fifth race of the 2010 NASCAR Sprint Cup Series season. This race marked the last appearance of the rear wing on the Car of Tomorrow, with the spoiler returning the following race. This race also was the first of three in Carl Edwards' probation following his altercation with Brad Keselowski at the previous race at Atlanta Motor Speedway, in which Keselowski went airborne, subsequently crashing on his side door. The race had 39 lead changes among 13 different leaders and 10 cautions. The race attendance of 138,000 marked the end of a long streak of sellout seats at the track, which has a capacity of 158,000. The race had been a sellout since 1982. Draconian regulations kept intact since the 1970s along with rising ticket prices and unexciting restrictor plate races at Talladega and Daytona helped to contribute to the empty seats at NASCAR races in addition to declining TV ratings.

Mike Rife, of Vansant Church of Christ, gave the Invocation. Steve Austin gave the command "Gentlemen, start your engines!".
