The Southernmost Point is a public monument commemorating the disputed southernmost point in the continental United States, marked by an anchored concrete buoy that is maintained by the Public Works Department of Key West.

The buoy was originally dedicated in September of 1983 as a public monument and stands 12 feet tall, located at 18 feet above sea level at the intersection of Whitehead and South Streets. It is one of the most-photographed monuments in the United States, serving as a popular gathering place for area tourists. From the buoy site, Cuba lies approximately 90 miles directly south. Though the site is commemorated as a major tourist attraction, two sites within the Florida Keys are believed to lie at lower latitudes, including the island of Ballast Key and a private site on the US Navy Truman Annex property.
