The 2015 Daytona 500, the 57th running of the event, was a NASCAR Sprint Cup Series race which was held on February 22, 2015 at Daytona International Speedway in Daytona Beach, Florida. Contested over 203 laps – extended from 200 laps due to a green–white–checker finish – on the 2.5 mi (4.0 km) asphalt superspeedway, it was the first race of the 2015 NASCAR Sprint Cup Series season. Joey Logano won the race, recording the second Daytona 500 win for Team Penske, and his ninth career Sprint Cup victory. Kevin Harvick finished second while Dale Earnhardt Jr., Denny Hamlin and Jimmie Johnson rounded out the top–five.

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.
