The Calumet River () is a system of heavily industrialized rivers and canals in the region between the neighborhood of South Chicago in Chicago, Illinois, and the city of Gary, Indiana. Historically, the Little Calumet River and the Grand Calumet River were one, the former flowing west from Indiana into Illinois, then turning back east to its mouth at Lake Michigan at Marquette Park in Gary.
