U.S. Highway 8 (US 8) is a United States Numbered Highway that runs primarily east–west for 280 miles (451 km), mostly within the state of Wisconsin. It connects Interstate 35 (I-35) in Forest Lake, Minnesota, to US 2 at Norway in the Upper Peninsula of Michigan near the border with Wisconsin. Except for the short freeway segment near Forest Lake, and sections near the St. Croix River bridge and Rhinelander, Wisconsin, it is mostly undivided surface road. As a state highway in the three states, US 8 is maintained by the Minnesota, Wisconsin and Michigan departments of transportation (Mn/DOT, WisDOT, MDOT, respectively).

The highway was originally commissioned on November 11, 1926, with the rest of the original U.S. Highway System. At the time, it ran between Forest Lake, Minnesota, and Pembine, Wisconsin, with a planned continuation to Powers, Michigan. Several changes have been made to the routing of the highway since then. The western end was extended south to Minneapolis before it was truncated back to Forest Lake. Other changes on the east end have moved that terminus from the originally planned end location at Powers to the current location in Norway. Internal Wisconsin and Michigan DOT map files at various times have shown plans to reroute the highway to connect to the original 1926 terminus. US 8's course through the three states has also been shifted to follow different alignments over the years.
