The 2008 NASCAR Nationwide Series was the 27th season of the NASCAR Nationwide Series, the second-tier professional stock car racing series sanctioned by NASCAR in the United States. The season began on February 16 at Daytona International Speedway with the Camping World 300, and ended on November 15 at Homestead-Miami Speedway with the Ford 300. This was the first season in which NASCAR's second-tier series was known as the Nationwide Series, ending the 26-year sponsorship by Anheuser-Busch's Busch Beer. The seven-year agreement gives Nationwide Insurance the exclusive rights to tie its brand to NASCAR's second most popular racing series.
