The East North Central states is a region of the United States defined by the U.S. Census Bureau, containing five states: Illinois, Indiana, Michigan, Ohio and Wisconsin. These states border the Great Lakes, West North Central, the Southeastern, and Northeastern states; the Eastern North Central states also share a land border with Canada through Michigan's Upper Peninsula, southeastern, and mid-Michigan regions. As one of two subregional divisions used to categorize the Midwest, East North Central closely matches the area of the Northwest Territory, excluding a portion of Minnesota.
