List of Guano Island claims
The United States claimed a number of islands as insular areas under the Guano Islands Act of 1856. Only the eight administered as the US Minor Islands and one each annexed by American Samoa and Hawaii remain as possessions of the United States. Any other unresolved claims if they exist are dormant, and have not been contested by the United States in many years with the exception of Navassa.
