State Trunk Highway 187 (often called Highway 187, STH-187 or WIS 187) is a state highway in the U.S. state of Wisconsin. It runs north–south in central Wisconsin from the intersection of WIS 54 near Shiocton to the junction of WIS 156 just west of Navarino. WIS 187 passes through sparsely populated, rural areas in the flat river valley of the Wolf River. The routing of the present WIS 187 has barely been changed since the introduction of the Wisconsin State Highway system in the 1920s.
