The Skokie River (or East Fork of the North Branch of the Chicago River) is a 20-mile-long (32 km) river that flows through the northern suburbs of Chicago, Illinois. It flows almost parallel to the shore of Lake Michigan, and historically discharged its outflow into that lake via the Chicago River. However, the construction of the Chicago Sanitary and Ship Canal in 1900 caused the drainage of the Chicago River, including its Skokie River tributary, to flow southwestward towards the Mississippi River.
The Skokie River rises from a flat area, historically a wetland, on the west side of the city of Waukegan. Flowing southward through the North Shore suburbs of Lake County, the river enters Cook County and discharges its flow into the North Branch of the Chicago River at Wilmette Golf Club between Morton Grove and Wilmette.
