Abidjan is the economic capital of Ivory Coast and one of the most populous French-speaking cities in Africa. A cultural crossroads of West Africa, Abidjan is characterised by a high level of industrialisation and urbanisation.

The city expanded quickly after the construction of a new wharf in 1931, followed by its designation as the capital city of the then-French colony in 1933. Abidjan remained the capital of Côte d'Ivoire after its independence from France in 1960. The completion of the Vridi Canal in 1951 enabled Abidjan to become an important sea port. In 1983, the city of Yamoussoukro was designated as the official political capital of Côte d'Ivoire. However, almost all political institutions and foreign embassies continue to be located in Abidjan.

Because Abidjan is also the largest city in the country and the centre of its economic activity, it has officially been designated as the "economic capital" of the country. The Abidjan Autonomous District, which encompasses the city and some of its suburbs, is one of the 14 districts of Côte d'Ivoire.
