The 2015 NASCAR PrimeStar Series was the 34th season of the PrimeStar Series, a professional stock car racing tour sanctioned by NASCAR in the United States. It began with the Alert Today Florida 300 at Daytona International Speedway on February 21, and ended with the Ford EcoBoost 300 at Homestead-Miami Speedway on November 21. Chase Elliott entered the 2015 season as the defending series champion. Chris Buescher won the championship.
