O'Reilly Raceway Park at Indianapolis, known as Indianapolis Raceway Park until the 2006 purchase of naming rights by O'Reilly Auto Parts, is a multipurpose racing facility located in Indianapolis, Indiana. It is not to be confused with Indianapolis Motor Speedway (IMS), which is often referred to as a superspeedway, although its construction vastly predates the use of that term. Surprisingly to some, the vast majority of motorsports events held in Indianapolis are held at Raceway Park, including a NASCAR Craftsman Truck Series race, a NASCAR Nationwide Series event, a midget car racing event, drag racing and road racing.
Sprint car races and other events suited to a shorter track are held here. Raceway Park also traditionally stages an extensive programs on the Saturday nights of major races at the big track nearby, with the Saturday night of Memorial Day weekend (late May) called the Night before the 500. The event is held the night before the Indianapolis 500 event at IMS, serving as something of an unofficial preliminary event to the far more famous one. Similarly, the Kroger NASCAR 200 was given a "Night before the 400" status. When Formula One raced at IMS, midget, sprint, and stock car races were held at ORP in the "Night Before F1" meets, including the 2002 and 2003 USGP races that featured a twin 25-lap midget format, with a full inversion, and the winner winning $50,000 if he could win both features.
The facility also includes a , 15-turn road course used for Sports Car Club of America "club" road racing events, featuring a long drag strip that hosts the annual NHRA U.S. Nationals on Labor Day weekend.
NOTE: The Kroger 200 is the only Nationwide Series race to carry the same primary sponsor for all 25 years of the series.
