Clam Falls is a town in Polk County, Wisconsin, United States.

The unincorporated communities of Clam Falls and Lewis are located in the town.

[3] The St. Croix Band of Lake Superior Chippewa Indians still inhabit the area, where they are engaged in harvesting wild rice, hunting, fishing, and maple sugaring.

The east and west bank of the river were the location of logging operations since the late 1840s, and the dam was constructed in 1859 by Daniel F. Smith.

Smith would go on to improve the Butternut Road, which became known as the Clam Falls Road—a highly travelled roadway extending from Clam Falls to Butternut Lake near present-day Luck, WI.
