The Allstate 400 at The Brickyard, introduced as the Brickyard 400 in 1994, is an annual 400-mile Sprint Cup points race held at the Indianapolis Motor Speedway in Speedway, Ind. The event, when first held in 1994, marked the first race other than the Indianapolis 500 to be held at the Indianapolis Motor Speedway since 1916. Since the inaugural race, the Allstate 400 has become NASCAR's most-attended event, drawing an estimated crowd of more than 250,000 fans annually. It also has become NASCAR's second-highest paying race in dollars behind the Daytona 500.

The term "Brickyard" is in reference to the nickname historically used for the Indianapolis Motor Speedway since 1910. The course was paved in brick in 1909 and a three foot strip of brick remains at the start/finish line.

Jimmie Johnson won the 2008 race en route to his third straight championship.
