The 2011 Daytona 500, the 53rd running of the event, was held on February 20, 2011 at Daytona International Speedway in Daytona Beach, Florida as the first race of the 2011 NASCAR Sprint Cup season. Trevor Bayne, driving for Wood Brothers Racing, won the race becoming the youngest Daytona 500 winner. Carl Edwards finished second, while David Gilliland, Bobby Labonte, and Kurt Busch rounded out the Top 5. Bayne had taken the lead shortly before the final restart and maintained it to win his first Cup Series race and Wood Brothers' fifth Daytona 500.

The Daytona 500 is a 500-mile-long (805 km) NASCAR Cup Series motor race held annually at Daytona International Speedway in Daytona Beach, Florida. It is the first of two Cup races held every year at Daytona, the second being the Coke Zero Sugar 400, and one of three held in Florida, with the annual fall showdown Dixie Vodka 400 being held at Homestead south of Miami. From 1988 to 2019, it was one of the four restrictor plate races on the Cup schedule. The inaugural Daytona 500 was held in 1959 coinciding with the opening of the speedway and since 1982, it has been the season-opening race of the Cup series.
