Tromelin Island (; French: Île Tromelin, pronounced) is a low, flat, island in the Indian Ocean about 500 kilometers north of Réunion, and about 450 kilometres (280 mi) east of Madagascar. Tromelin is administered as a French overseas territory; however, Mauritius claims sovereignty over the island, on grounds of its absence in the listing of the 8th article of the French version of the 1814 Paris Treaty. France and Mauritius have been negotiating for years in regard to a possible co-management of the island in the future. Tromelin has facilities for scientific expeditions and a weather station. It is a nesting site for birds and green sea turtles.
