Lagos

Lagos, or Lagos City, is a large metropolitan port city in southwestern Nigeria. As of November 2025, the size of the city's population has been estimated to be between 17 and 21 million residents, making Lagos the largest city in Nigeria, the most populous urban area on the African continent, and one of the fastest-growing megacities in the world. Lagos was the national capital of Nigeria until the government's December 1991 decision to relocate its capital to Abuja, in the centre of the country. Apart from serving as a major African financial center, Lagos has also played a significant role in the national economy, serving as the economic hub of Lagos State and the entire country of Nigeria. The city has a significant influence on commerce, entertainment, technology, education, politics, tourism, art, and fashion in Africa. Lagos is also among the top ten of the world's fastest-growing cities and urban areas. A megacity, it has the second-highest GDP in Africa, and houses one of the largest and busiest seaports on the continent. Due to the large urban population and port traffic volumes, Lagos is classified as a Medium-Port Megacity.
