Rose Island, also known as Rose Atoll or Motu O Manu, is a secluded Marine National Monument located in American Samoa. This nearly square atoll is one of the smallest in the world and marks the southernmost point belonging to the United States. Managed cooperatively by the U.S. Fish and Wildlife Service and the local government, it is a critical sanctuary for nesting seabirds and diverse marine species. The atoll consists of a vibrant lagoon, reef flats, and two small islets—Rose and Sand Island. Due to its extreme isolation, roughly 140 km from the nearest island, it remains an undisturbed haven for ecological research and conservation.
