Defining the "Eastern United States" can vary by context—geological, cultural, or political—but a common core grouping includes the nine states listed below. These states generally encompass the New England and Mid-Atlantic regions.
Note that broader definitions often extend southward to include states like Maryland, Delaware, Virginia, and the Carolinas, or westward to the Great Lakes states. However, the list above represents the traditional northeastern core often referred to in historical and cultural discussions of "the Eastern states."
