The Four Corners Monument marks the quadripoint in the Southwestern United States where the states of Arizona, Colorado, New Mexico, and Utah meet. It is the only point in the United States shared by four states, leading to the area being named the Four Corners region. The monument also marks the boundary between two semi-autonomous Native American governments, the Navajo Nation, which maintains the monument as a tourist attraction, and the Ute Mountain Ute Tribe Reservation.

A quadripoint is a point on Earth where four distinct political territories meet. The territories can be of different types, such as national and provincial. In North America, several such places are commonly known as Four Corners. Several examples exist throughout the world that use other names.
