This is a list of all tripoints in which the boundaries of three (and only three) U.S. states converge at a single geographic point. Of the 60 such points, 36 are on dry land and 24 are in water.[1] Of the points in water, 3 are in the Great Lakes and thus have no land nearby. A tripoint occurring in a populated area may also be informally described as a tri-state area.
