Iowa Highway 188 (Iowa 188) is a state highway in north-central Iowa. The route is signed both north–south and east–west because of a 90-degree corner near the route's midpoint. The route begins at Iowa Highway 3 south of Clarksville and ends at U.S. Highway 63 near Tripoli.

History
Iowa 188 was designated in 1945 as a 10-mile-long (16 km) route which connected
US 63. It first appeared on the state highway map in 1946.[2] Four years later, the highway absorbed Iowa 53, which connected Clarksville to Iowa 10.[3] Until 1963, the highway appeared very much like it does today. That year the section of highway between Clarksville and Plainfield was turned over to Butler County officials and the section south of Clarksville became Iowa 122.[4] Just three years later, the Iowa State Highway Commission changed course and reabsorbed Iowa 122. Since then the routing has not changed.[5]
