Flint Island is an uninhabited coral atoll in the central Pacific Ocean, part of the Southern Line Islands under the jurisdiction of Kiribati. In 2014 the Kiribati government established a twelve-nautical-mile (22-kilometre; 14-mile) exclusion zone around each of the southern Line Islands (Caroline (commonly called Millennium), Flint, Vostok, Malden, and Starbuck).
