State Trunk Highway 175 (often called Highway 175, STH-175 or WIS 175) is a state highway in the US state of Wisconsin. It runs north–south in central Wisconsin from West Milwaukee to just south of Fond du Lac.

The highway follows the former route of U.S. Highway 41 (US 41) before US 41's current route was created between 1953 and 1955. Portions of the highway were part of the Yellowstone Trail. North Fond du Lac created a park dedicated to the trail, which was the first transcontinental automobile highway through the upper tier of states in the United States.
