Juan de Nova Island is a small, uninhabited island located in the Indian Ocean. It is part of the French Southern and Antarctic Lands, which is a territory of France. The island is located between Madagascar and Mozambique, and is roughly 6 kilometers long and 1.6 kilometers wide.

The island was discovered by the Portuguese in the early 16th century, and was later claimed by France in 1897. Today, the island serves as a protected nature reserve, and is home to a variety of bird species, including frigate birds, boobies, and terns. It is also home to a number of sea turtle species, including green and hawksbill turtles, which nest on the island's beaches.

Juan de Nova Island is a popular destination for birdwatchers and nature enthusiasts, and is known for its pristine beaches and crystal-clear waters. However, access to the island is restricted, and visitors must obtain permission from the French authorities in order to visit.
