Juan de Nova Island (French: Île Juan de Nova, pronounced [il ʒɥɑ̃ də nɔva]), Malagasy: Nosy Kely) is a French-controlled tropical island in the narrowest part of the Mozambique Channel, about one-third of the way between Madagascar and Mozambique. It is a low, flat island, 4.8 square kilometres (1.9 sq mi) in size.
Administratively, the island is one of the Scattered islands in the Indian Ocean, a district of the French Southern and Antarctic Lands. However, its sovereignty is disputed by Madagascar.
