The Southeastern United States, also referred to as the American Southeast, the Southeast, or the South, is a geographical region of the United States located in the eastern portion of the Southern United States and the southern portion of the Eastern United States. The region includes a core of states that reaches north to Maryland and West Virginia, bordering the Ohio River and Mason–Dixon line, and stretches west to Arkansas and Louisiana.[note 2]
