The Des Plaines River (/dɪsˈpleɪnz/ diss-PLAYNZ) (French: Rivière des Plaines) is a river that flows southward for 133 miles (214 km) through southern Wisconsin and northern Illinois in the United States Midwest, eventually meeting the Kankakee River west of Channahon to form the Illinois River, a tributary of the Mississippi River.
Native Americans used the river as transportation route and portage. When French explorers and missionaries arrived in the 1600s, in what was then the Illinois Country of New France, they named the waterway La Rivière des Plaines (River of the Plains). The local Native Americans showed these early European explorers how to traverse waterways of the Des Plaines watershed to travel from Lake Michigan to the Mississippi River and its valley.
Parts of the river are now part of the Illinois Waterway and the Chicago Area Waterway System.
