Kinnickinnic River (Milwaukee River tributary)

The Kinnickinnic River is a river in southeastern Wisconsin, United States. The river is 9.6 miles (15.4 km) long and flows east from its source in Milwaukee County, Wisconsin toward downtown Milwaukee, where it joins the Milwaukee River and the Menomonee River before emptying into Lake Michigan. It is locally called the "KK River".

Kinnickinnic is an Ojibwe word that literally means "what is mixed", referring to the mixing of indigenous plants and tobaccos. Often called Milwaukee's forgotten river, it is the smallest within the Milwaukee River Basin, yet is the most urbanized and densely populated, as it winds through the Lincoln Village neighborhood and the heavily industrialized Inner Harbor.
