Historic regions of the United States
This is a list of historic regions of the United States that existed at some time during the territorial evolution of the United States and its overseas possessions, from the colonial era to the present day. It includes formally organized territories, proposed and failed states, unrecognized breakaway states, international and interstate purchases, cessions, and land grants, and historical military departments and administrative districts. The last section lists informal regions from American vernacular geography known by popular nicknames and linked by geographical, cultural, or economic similarities, some of which are still in use today.
For a more complete list of regions and subdivisions of the United States used in modern times, see List of regions of the United States.
