State Trunk Highway 175 (often called Highway 175, STH 175 or WIS 175) is a state highway in the U.S. state of Wisconsin. It runs north–south in central Wisconsin from in Milwaukee to just south of Fond du Lac.
The highway follows the former route of U.S. Highway 41 before 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.
The highway was shorted by 17.1 miles (27.5 km) on January 1, 2007. The northern terminus was moved from U.S. Route 45 near Oshkosh to its present location near Fond du Lac. The portion in Winnebago County became County Highway R, and the portion in Fond du Lac County (including through the Van Dyne, North Fond du Lac, and Fond du Lac communities) became County Highway RP.

Numerous segments of the highway are marked for changing to local control, including segments in Washington County.
