State Trunk Highway 171 (often called Highway 171, STH-171 or WIS 171) is a state highway in the U.S. state of Wisconsin. It runs east–west in southwest Wisconsin from near Ferryville to Boaz. A section of the route was initially designated as WIS 131 in 1924, but it was not signed as WIS 171 until sometime between 1948 and 1956, when the highway was extended east to US 14 near Boaz.
