Tri-state area

Tri-state area ^{[1] [2]} is an informal term in the United States which can refer to any of multiple areas that lie across three states. When referring to populated areas, the term implies a shared economy or culture among the area's residents, typically concentrated around a central metropolis.

Tri-state areas may or may not include a state boundary tripoint.
