Tromelin Island (/ˌtroʊmlɪn ˈaɪlənd/; French: Île Tromelin, pronounced: [il tʁɔmlɛ̃]) is a low, flat, island in the Indian Ocean, about 450 kilometres (280 mi) east of Madagascar. It is administered as a French overseas territory, as the result of an agreement with the United Kingdom in 1954, but sovereignty is disputed with ownership claimed by both Mauritius and the Seychelles. It has a weather station and is a nesting site for boobies and green sea turtles.
