Traverse des Sioux is a historic site in the U.S. state of Minnesota. Once part of a preindustrial trade route, it commemorates that route, a busy river crossing on it, a nineteenth-century settlement, trading post, and mission at that crossing place, a transshipment point for pelts in fur trading days, and an important treaty with Native Americans which dispossessed the Dakota people of part of their homeland and opened up much of southern Minnesota to white settlement.
