Dominica, an island in the eastern Caribbean Sea, lies at the midpoint of the Lesser Antilles, between the French possessions of Guadeloupe to the north and Martinique to the south. It is often, but not always, considered one of the Windward Islands. With an area of 754 square kilometers (291 square miles), Dominica is slightly more than twice as large as the state of New Hampshire. The lush vegetation and abundant wildlife of the country's rain forests have led Dominica to proclaim itself "The Nature Island of the Caribbean."
Dominica claims no territories or dependencies.
