Luanda, formerly named São Paulo da Assunção de Loanda, is the capital and largest city of Angola. Located on Angola's coast with the Atlantic Ocean, Luanda is both Angola's chief seaport and its administrative center. It has a population of over 5 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.

The city is currently undergoing a major reconstruction, with many large developments taking place that will alter the cityscape significantly. Luanda was ranked the most expensive city to live in for expatriates by Mercer, for 2011.
