A triple border, tripoint, trijunction, triple point, or tri-border area is a geographical point at which the boundaries of three countries or subnational divisions meet. As of 2020, there are 175 international tripoints in the world. Nearly half are situated in rivers, lakes or seas. On dry land, the exact tripoints may be indicated by markers or pillars, and occasionally by larger monuments.
