The Whitefish Bay National Forest Scenic Byway is a National Forest Scenic Byway that runs along Whitefish Bay in the Hiawatha National Forest in the U.S. state of Michigan. The byway mostly follows Federal Forest Highway 42 (FFH 42) through Chippewa County in the Upper Peninsula. As a forest highway, it is maintained jointly by the Chippewa County Road Commission (CCRC) and the U.S. Forest Service (USFS). The route of the byway first existed as an earth road by the 1930s; it was improved into a gravel road in the 1940s and paved between the 1950s and the 1980s. The byway designation was created in 1989.
