Traverse des Sioux is a historic site in the U.S. state of Minnesota. Once part of a pre-industrial trade route, it is preserved to commemorate that route, a busy river crossing on it, and a nineteenth-century settlement, trading post, and mission at that crossing place. It was a transshipment point for pelts in fur trading days, and the namesake for an important United States treaty that forced the Dakota people to cede part of their homeland and opened up much of southern Minnesota to European-American settlement.
