The Illiana Motor Speedway is a closed race track located in Schererville, Indiana, United States and was built in 1947.

During the 1962 season the track's owner Harry Molenaar created a season-ending 100-lap race called the "Tony Bettenhausen Memorial" dedicated to the memory of former open wheel Indy car and local racer Tony Bettenhausen who died a year earlier in a racing accident.

In 2000 the speedway was repaved for the first time in nearly 40 years and current owner Mike Mikuly bought the track and also installed cement walls to replace the old guard rails.

In 2000 the Turbo Stox division was introduced with great success racing on Illiana's 1/4 mile.

On June 24, 2016 the town of Schererville announced it had purchased the track and would begin demolition of the speedway.
