罗安达（葡萄牙语：Luanda，原称：São Paulo da Assunção de Loanda）或译卢安达，位于安哥拉西部大西洋沿岸，是该国首都和第一大城市，也是重要的港口和是全国政治、文化、经济和交通的中心。

罗安达是安哥拉的首都，是濒临大西洋海岸中段的一座欧洲式港口城市，具有浓厚的葡萄牙风味。它位于撒哈拉以南，是欧洲移民最早在安哥拉境内所创建的城市，市内有铁路通往马兰热。

经过内战后的重建，该市开始建起较为现代的商业大楼、酒店等现代化设施；但是城区建筑布局较为混乱，交通极为拥堵。一座本只应容纳50万人口的城市，都会区如今容纳了将近500万人，从而造成一系列社会问题，例如交通拥挤，治安恶化，卫生问题等。

Luanda, formerly named São Paulo da Assunção de Loanda, is the capital and largest city in Angola, and the country's most populous and important city, primary port and major industrial, cultural and urban centre. Located on Angola's coast with the Atlantic Ocean, Luanda is both Angola's chief seaport and its administrative centre. It has a metropolitan population of over 6 million. It is also the capital city of Luanda Province, and the world's third most populous Portuguese-speaking city, behind only São Paulo and Rio de Janeiro, both in Brazil, and the most populous Portuguese-speaking capital city in the world, ahead of Brasília, Maputo and Lisbon.
