There are a number of places in the [[United States]] known as '''tri-state areas''' where three [[U.S. state|state]]s or holdings meet at one point (a [[tripoint]]), or in proximity to each other. The two most well-known are for the [[New York City|New York]] and [[Chicago]] metropolitan areas.

The [[Tri-State Region]] around New York City is where [[New York]], [[New Jersey]], and [[Connecticut]] meet. There is no tripoint, however, as Connecticut does not touch New Jersey. Chicago's tri-state region includes [[Illinois]], [[Indiana]], and [[Wisconsin]] and is commonly referred to as [[Chicagoland]]. This tri-state region also does not have a tripoint since Indiana does not touch Wisconsin.

Other large metropolitan areas with a tri-state area include [[Cincinnati, Ohio|Cincinnati]], [[Memphis, Tennessee|Memphis]], [[Philadelphia, Pennsylvania|Philadelphia]], and [[Washington, D.C.]]

The "Joplin District" Lead-Zinc Mining region of Oklahoma, Kansas and Missouri produced mineral specimens famous throughout the world know as "Tri-State" minerals.
