Antananarivo is the capital and largest city of Madagascar. The administrative area of the city, known as Antananarivo-Renivohitra ("Antananarivo-Mother Hill" or "Antananarivo-Capital"), is the capital of Analamanga region. The city sits at 1,280 m (4,199 ft) above sea level in the center of the island, the highest national capital by elevation among the island countries. It has been the country's largest population center since at least the 18th century. The presidency, National Assembly, Senate and Supreme Court are located there, as are 21 diplomatic missions and the headquarters of many national and international businesses and NGOs. It has more universities, nightclubs, art venues, and medical services than any city on the island. Several national and local sports teams, including the championship-winning national rugby team, the Makis are based here.

The city is now managed by the Commune Urbaine d'Antananarivo (CUA) under the direction of its President of the Special Delegation, Ny Havana Andriamanjato, appointed in March 2014. Limited funds and mismanagement have hampered consecutive CUA efforts to manage overcrowding and traffic, waste management, pollution, security, public water and electricity, and other challenges linked to explosive population growth. Major historic landmarks and attractions in the city include the reconstructed royal palaces and the Andafiavaratra Palace, the tomb of Rainiharo, Tsimbazaza Zoo, Mahamasina Stadium, Lake Anosy, four 19th-century martyr churches, and the Museum of Art and Archaeology.
