Madagascar is an island nation in the Indian Ocean, roughly 400 kilometers off the southeastern coast of Africa. Commonly described as the fourth largest island in the world, it separated from other landmasses more than 60 million years ago, and that long isolation left it with one of the highest concentrations of plants and animals found nowhere else on Earth.

Where Is Madagascar Located?

Madagascar lies in the Indian Ocean off the southeastern coast of the African continent, separated from Mozambique by the Mozambique Channel. Its combination of coastline, central highlands, and long geological isolation makes it geographically distinct from mainland Africa despite the short distance between them.

Geography of Madagascar

The island covers roughly 587,000 to 592,000 square kilometers, depending on the measurement source, with a highland central plateau fringed by low lying coastal plains. Its climate ranges from tropical along the coasts to temperate inland and arid in the south. Two thirds of the population lives in coastal zones exposed to cyclones, and the country has been struck by 35 cyclones, 8 major floods, and 5 severe droughts over the past 20 years, according to United Nations Environment Programme data. Among its most distinctive geological features is Tsingy de Bemaraha, a limestone karst landscape of razor sharp pinnacles carved by rain and groundwater, protected as a UNESCO World Heritage Site since 1990.

A Brief History of Madagascar

Madagascar’s population traces its origins primarily to Austronesian settlers who sailed more than 3,000 miles from the direction of Indonesia, later joined by migration and cultural influence from mainland Africa, giving the island an unusually blended Austronesian and African heritage found nowhere else in the region. France annexed Madagascar as a colony in 1896, administering it until independence in 1960. In 2025, Madagascar experienced a period of significant political instability, including large protests and a change in its leadership; as this is an evolving situation, readers should look to current reporting for the latest details on its government rather than treating any single description of officeholders as settled.

Government and Economy

Under its 2010 constitution, Madagascar is structured as a semi presidential republic, with an elected president as head of state, a prime minister as head of government, and a bicameral parliament. Given the instability noted above, the country’s day to day governing arrangement should be treated as unsettled rather than fixed.

Economically, Madagascar is among the world’s lower income countries, with a poverty rate estimated at 66.5 percent in 2025 by the World Bank. Growth has averaged around 3 percent annually in recent years, supported by manufacturing, services, tourism, and telecommunications, alongside continued reliance on subsistence agriculture and exports such as garments and essential oils.

Culture and People

Malagasy and French are Madagascar’s official languages. According to the country’s 2018 census, the population stood at 25,674,196, with more than 80 percent living in rural areas and a notably young age structure, nearly half of residents were under 18. The capital is Antananarivo.

What Is Madagascar Known For?

Madagascar is globally recognized as one of the world’s most important biodiversity hotspots. An estimated 90 percent of its plants and 85 percent of its non flying animal species are endemic, found nowhere else on the planet. Its lemurs, roughly 100 species found only on the island, are its best known ambassadors, though nearly all are now considered threatened with extinction. Peer reviewed genomic research has also identified Madagascar as the evolutionary center of origin for baobab trees, home to six of the world’s eight baobab species. The single most photographed and internationally recognized image of the country is the Avenue of the Baobabs near Morondava, a dirt road lined with towering, barrel trunked Grandidier’s baobabs, a species now listed as endangered.

Why Madagascar Matters

Madagascar matters to science and conservation out of proportion to its size, because its unique evolutionary history cannot be found or replaced anywhere else. More than 18 million Malagasy people also depend directly on the island’s natural resources for their livelihoods, which means the same forests and reefs that make Madagascar scientifically irreplaceable are also central to the everyday survival of its population, tying conservation and human welfare together in a way few other places illustrate as clearly.

Key Takeaways

• Madagascar is an island nation in the Indian Ocean, commonly described as the fourth largest island in the world.
• More than 60 million years of isolation gave it exceptionally high rates of endemism, an estimated 90 percent of plants and 85 percent of non flying animals found nowhere else.
• Its population descends primarily from Austronesian settlers with later African influence, a distinctive combination for an island off Africa’s coast.
• France ruled Madagascar as a colony from 1896 until independence in 1960; the country experienced significant political instability in 2025.
• The Avenue of the Baobabs near Morondava is the island’s most internationally recognized image, though Tsingy de Bemaraha’s karst landscape is also a UNESCO World Heritage Site.
