The United Nations Educational, Scientific and Cultural Organization (UNESCO) World Heritage Sites are places of importance to cultural or natural heritage as described in the 1972 UNESCO World Heritage Convention. Cultural heritage consists of monuments (such as architectural works, monumental sculptures, or inscriptions), groups of buildings, and sites (including archaeological sites). Natural heritage consists of natural features (physical and biological formations), geological and physiographical formations (including habitats of threatened species of animals and plants), and natural sites which are important from the point of view of science, conservation, or natural beauty. Madagascar ratified the convention on July 19, 1983, making its historical sites eligible for inclusion on the list. As of 2025, there are three World Heritage Sites in Madagascar. Madagascar served on the World Heritage Committee from 2005 to 2009.
The first site in Madagascar, the Strict Nature Reserve of the Tsingy of Bemaraha, was inscribed on the list as a site of natural importance at the 14th Session of the World Heritage Committee, held in Banff, Canada in 1990. This was followed by the 2001 inscription of the Royal Hill of Ambohimanga, a historic village and royal palace compound of cultural importance featuring well-preserved 19th-century palaces and numerous other natural and architectural features of historic, political and spiritual significance to the Malagasy people. Most recently, in 2007 the natural site of the Rainforests of the Atsinanana was added to the list, comprising a cluster of six national parks distinguished by their highly endemic biodiversity. A fourth site, the capital of the 19th century Merina sovereigns of Madagascar at the Rova of Antananarivo, had originally been slated to become the nation's first cultural World Heritage Site in 1995 but was destroyed by a fire shortly before the inscription was finalized. UNESCO placed the Rainforests of the Atsinanana on the list of World Heritage in Danger on July 30, 2010, following an increase in illegal logging in the parks since 2009 as a consequence of the 2009-2013 political crisis in Madagascar.
