The Samsung Mobile 500 is a NASCAR Sprint Cup Series race held at the Texas Motor Speedway in Fort Worth, Texas USA. Even though is advertised as a "500 mile" race, because TMS is a 1.5 miles (2.4 km) track, the actual distance is 501 miles (806.3 km). There were 10 different winners in the first ten races, the longest such streak for any NASCAR track in the Cup Series. Jeff Burton, the winner of the first Cup race, broke that streak by getting his second Texas win in a last lap pass in 2007. Now starting in 2011, the race will become a Saturday night event, whereas before it was always a Sunday afternoon race. This was done since the night race at Phoenix was moved to February and became a day race. The 2011 race was run on April 9, 2011 and it was the first scheduled night race of the year.

Samsung sponsors the race, and RadioShack was previously a co-sponsor. The joint sponsorship was grandfathered in 2003 by NASCAR's grandfather clause when Nextel became a NASCAR sponsor, as they banned rival wireless sponsorships (Nextel uses Motorola exclusively); the ban was lifted after the 2005 merger of Sprint and Nextel because Sprint is sold at RadioShack, and Sprint offers Samsung products.
