Tri-state area
Tri-state area is an informal term in the eastern contiguous United States for any of several regions associated with a particular town or metropolis that, with adjacent suburbs, lies across three states. Some of these involve a state boundary tripoint. Other tri-state areas have a more diffuse population that shares a connected economy and geography—especially with respect to geology, botany, or climate—such as the tri-state area of New York, New Jersey, and Connecticut. The term "tri-state area" often occurs in movies and radio and television commercials.

This area is colloquially referred to as "the DMV" (DC, Maryland, Virginia).
