Navassa Island is an uninhabited island in the Caribbean Sea, located about 55 kilometers (34 miles) west of Haiti and 150 kilometers (93 miles) south of Cuba. It is an unorganized, unincorporated territory of the United States and is under the jurisdiction of the U.S. Fish and Wildlife Service.

Navassa Island is just 5.2 square kilometers (2 square miles) in size, and consists of coral reefs, rocky cliffs, and a few scattered areas of vegetation. It is primarily a wildlife refuge, and its remote location and difficult terrain make it a challenging place to visit or work.

The island is home to a variety of plant and animal species, including several that are endangered or threatened, such as the hawksbill sea turtle, brown booby bird, and Navassa Island iguana. Due to its importance as a nesting site for these and other species, access to the island is heavily restricted.

Navassa Island has a complex history, with various groups claiming ownership over the centuries. In 1857, the United States claimed the island under the Guano Islands Act, which granted the U.S. government the right to claim uninhabited islands with guano deposits. However, disputes over ownership continued until 1898, when the U.S. Supreme Court ruled in favor of the United States.

Today, Navassa Island remains a largely untouched wilderness, protected for the benefit of its unique wildlife and ecosystem.
