Motu One (Marquesan for "Sand Island"; French: Îlot de Sable) is the name of a small sandbank with no vegetation located on the western edge of a coral reef. The reef is approximately 5 kilometres (3.1 mi) in diameter and the islet or islets are less than a hectare in surface, rising only a few feet above sea level and changing shape regularly owing to the action of the currents. Motu One is administratively part of the commune (municipality) of Nuku-Hiva, itself in the administrative subdivision of the Marquesas.
