In the U.S. state of Wisconsin, the Northern Highland is a geographical region covering much of the state’s northern territory. The region stretches from the state border with Minnesota in the west to the Michigan border in the east, and from Douglas and Bayfield Counties in the north to Wood and Portage Counties in the south. While most of northern Wisconsin is within the Northern Highland region, a short belt of land along the coast of Lake Superior is not included in the area, and is instead part of the Lake Superior Lowland. Outside of Wisconsin, the highland stretches northward in Canada to Labrador and Hudson Bay.

The Northern Highland was once a mountain range similar to the Alps or Rocky Mountains of today. Over hundreds of millions of years, these mountains were worn down and flattened out by erosion and glaciation. Today the region is mostly a smooth plain, but it remains higher than the rest of the state and some hilly regions continue to exist. Located near the center of the region, Timms Hill in Price County is the highest point in Wisconsin. It has an elevation of 1,951 feet above sea level. Other hills such as Rib Mountain also approach this elevation.
