A map of most of the New York City metropolitan area.
The New York City metropolitan area is a real life metropolitan area in the United States, and Earth's largest by geographical area. With the New York City borough of Manhattan at its heart, the metropolitan area includes all of New York City as well as closely neighboring urban areas in the states of New York, New Jersey and Connecticut, which is what gives the area its other common name, the Tri-State Area. In the state of New York, the area includes part of the North American mainland north of the city as well as most of Long Island, but not most of the state itself.
A lion's share of events in the Teenage Mutant Ninja Turtles franchise take place in this region.
