The 2012 AAA 400 was a NASCAR Cup Series stock car race held on September 30, 2012 at Dover International Speedway in Dover, Delaware.
Contested over 400 laps, it was the twenty-ninth in the 2012 NASCAR Sprint Cup Series, as well as the third race in the ten-race Chase for the Sprint Cup, which ends the season.
Brad Keselowski of Team Penske won the race; this would ultimately be the last victory for a Dodge-based team in the Sprint Cup Series, as the season is the final season for Dodge in the Sprint Cup Series.
