International Speedway Corporation (NYSE: ISCA) is a corporation whose primary business is the ownership and management of NASCAR race tracks.

The corporation owns California Speedway, Darlington Raceway, Daytona International Speedway, Homestead-Miami Speedway, Kansas Speedway, Martinsville Speedway, Michigan International Speedway, Phoenix International Raceway, Richmond International Raceway, Talladega Superspeedway, and the Watkins Glen International road course and owns a minority interest in Chicagoland Speedway. Together these tracks hold slightly less than two-thirds of the events on the NASCAR Nextel Cup Series schedule. ISC has also agreed to purchase 600 acres (2.4 km²) on Staten Island in New York for the construction of a new speedway. In addition, the company owns the Motor Racing Network, a radio network that broadcasts NASCAR events, and Americrown, a food service business related to concessions at its tracks.

About 55% of the stock in ISC is owned by the heirs of NASCAR founder William H.G. France and the remainder trades on the stock market.

Although ISC is the private property of the France family, it is separate from NASCAR.
