Southern United States
- An expansive region encompassing the southeastern and south-central part of the United States, typically defined as including the states of Texas, Oklahoma, Louisiana, Arkansas, Alabama, Mississippi, Tennessee, Kentucky, Georgia, North Carolina, South Carolina, West Virginia, and Virginia, sometimes also Maryland, Delaware, Washington, D.C., and Missouri.
The term Southern United States is defined more by shared culture and history than strict geography. Although located in the extreme south of the United States, southern California, New Mexico, and Arizona are not considered part of it. In contrast, Virginia and West Virginia, though located in the middle of the east coast, are considered part of it.
