The Baraboo Range is a mountain range in Columbia County and Sauk County, Wisconsin. Geologically, it is a syncline fold consisting of highly eroded Precambrian metamorphic rock. It is about 25 miles (40 km) long and varies from 5 to 10 miles (16 km) in width. The Wisconsin River, previously traveling in a north to south direction, turns to the east just north of the range before making its turn to the west towards the Upper Mississippi River. The eastern end of the range was glaciated during the Wisconsinian glaciation, while the western half was not, and consequently, marks the eastern boundary of Wisconsin's Driftless Area.

The city of Baraboo is in the center of the valley. The range was designated a National Natural Landmark in 1980.[1]
