Lagos ( LAY-goss; Yoruba: Èkó [èkó]), 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.
Lagos emerged as a home to the Awori people, an Ijebu subgroup of the Yoruba of West Africa, in the 15th century, which is contained across the present-day Local Government Areas (LGAs) of Lagos Island, Eti-Osa, Amuwo-Odofin, and Apapa. Before the 15th century, the Awori settled on a farmstead along the coastal line, in and around which they worked and lived. Farmstead translates to Ereko in Yoruba, from which comes the Lagos indigenous name Eko. The lands are separated by creeks, fringing the southwest mouth of Lagos Lagoon, while being protected from the Atlantic Ocean by barrier islands and long sand spits such as Bar Beach, which stretch up to 100 km (62 mi) east and west of the mouth. Due to rapid urbanisation, the city expanded to the west of the lagoon to include areas in the present-day Lagos Mainland, Ajeromi-Ifelodun, and Surulere. This led to the classification of Lagos into two main areas: the Island, which was the original city of Lagos, and the Mainland, which it has since expanded into. This city area was governed directly by the Federal Government through the Lagos City Council until the creation of Lagos State in 1967, which led to the splitting of Lagos city into the present-day seven Local Government Areas (LGAs), and the addition of other towns (which now make up 13 LGAs) from the then Western Region to form the state.
However, in 1976, the state capital was later moved to Ikeja, and, in 1991, the federal capital was moved to Abuja. Even though Lagos is still widely referred to as a city, the present-day Lagos, also known as "Metropolitan Lagos", and officially as "Lagos Metropolitan Area" is an urban agglomeration or conurbation, consisting of 16 LGAs, including Ikeja, the state capital of Lagos State. While this conurbation encompasses 37% of Lagos State's total land area, it accommodates approximately 85% of the state's total population.

The population of Metropolitan Lagos is disputed. In the 2006 federal census data, the conurbation had a population of about 9 million people. However, the figure was disputed by the Lagos State Government, which later released its own population data, putting the population of Lagos Metropolitan Area at approximately 16 million. Daily, the Lagos area is growing by some 3,000 people or around 1.1 million annually, so the true population figure of the greater Lagos area in 2022 is roughly 28 million (up from some 23.5 million in 2018). Lagos may therefore have overtaken Kinshasa as Africa's most populous city. The Lagos conurbation is part of an emerging transnational megalopolis on the coast of West Africa that includes areas in five sovereign states, the Abidjan–Lagos Corridor.
The University of Lagos is one of the first-generation universities of Nigeria. The business district of Lagos is home to Tinubu Square, named after the aristocrat and slave trader Efunroye Tinubu. Lagos contains Murtala Muhammed International Airport, named after Murtala Muhammad, one of the former Nigerian presidents; the airport is one of the busiest African airports. Lagos National Stadium has hosted various international sports events, such as the 1980 African Cup of Nations.
Etymology
Lagos is derived from the Portuguese word for "lakes". The pronunciation (LAY-goss) is typically standard in British and Nigerian English. Due to the United States' much higher amount of placenames originating in Spanish - which is closely related to Portuguese - relative to Britain, speakers of American English often use the pronunciation (LAH-gohss), which is more similar to the original Portuguese pronunciation. The native Yoruba name Èkó is also used by Yoruba people. Lagos was most likely named after Lagos, Portugal, as it was the main centre of Portuguese maritime expeditions down the African coast in the 15th century.
Lagos was formerly the capital city of Nigeria, but it has since been replaced by Abuja. Abuja officially became the capital of Nigeria on 12 December 1991, although the decision to move the federal capital had been made fifteen years earlier, in Act No. 6 of 1976. Lagos is also home to the High Court of the Lagos State Judiciary, housed in an old colonial building on Lagos Island.
In terms of administration, Lagos is not a single municipality and therefore has no overall city administration. The geographical city limits of Metropolitan Lagos comprise 16 of the 20 Local Government Areas of Lagos State. The latter entity provides overall government for the metropolitan region. The former Municipality of Lagos, which covered Lagos Island, Ikoyi, and Victoria Island as well as some mainland territory, was managed by the Lagos City Council (LCC), but it was disbanded in 1976 and divided into several Local Government Areas (most notably Lagos Island LGA, Lagos Mainland LGA, and Eti-Osa LGA).
The mainland beyond the Municipality of Lagos, on the other hand, included several separate towns and settlements such as Mushin, Ikeja, and Agege. In the wake of the 1970s Nigerian oil boom, Lagos experienced a population explosion, untamed economic growth, and unmitigated rural migration. This caused the outlying towns and settlements to develop rapidly, thus forming the present-day "Lagos Metropolitan Area", also known as "Metropolitan Lagos". The history of Lagos is still evidenced in the layout of the LGAs that display the unique identities of the cultures that created them.
By 2006, the metro area around Lagos had extended beyond Lagos State's boundaries and attained a megacity status. This much larger area is referred to as "Greater Metropolitan Lagos" or "Lagos Megacity Region", which is a continuously built-up land area of an additional 1,535.4 square kilometres (592.8 square miles), in LGAs situated next to Lagos's eastern and western city limits in Lagos State, and also beyond its northern limits, spilling into some LGAs in adjoining Ogun State. Ogun State LGAs that have become part of Greater Metropolitan Lagos include Obafemi Owode, Sagamu, Ifo, Ado-Odo/Ota, and part of Ewekoro.
Today, the word Lagos most often refers to the urban area, called "Metropolitan Lagos" in Nigeria, which includes both the islands of the former municipality of Lagos and the mainland suburbs. The Lagos State government is responsible for some of the utilities, including roads and transportation, power, water, health, and education. Metropolitan Lagos extends over 16 of the 20 LGAs of Lagos State and contains about 85% of the population of Lagos State, including some semi-rural areas. Lagos has a considerable number of high-rise buildings that dominate its skyline. Most of the tall buildings are located in the downtown Central Business District.
Demography
Although the 2006 National Population Census of Nigeria credited the metropolitan area with a population figure of 7,937,932, the figure is at variance with some projections by the United Nations and other population agencies and groups worldwide. The population figure of Lagos State given by the Lagos State Government is 17,553,924. That figure was based on claimed conducted enumeration for social planning by the Lagos State Government's "parallel census" and it believes that since the inhabitants of the metropolitan area of Lagos constitute 88% of the Lagos State population, the population of metropolitan Lagos is about 15.5 million.
A rejoinder to Lagos State Government views concluded that Lagos State concealed the fact that the UN agencies' population projection for Lagos Urban Agglomeration had been revised downwards substantially as early as 2003. It failed to interpret the two most important and fairly representative and reliable secondary data sets already in the public domain, the National Identity Card Scheme and the 2003 Voters Registration figures from INEC. The figures for 2007 voter registration by INEC were an act sequel to the release of the provisional census results and comprehensively corroborated, vindicated, and validated the population figures.
According to the official results of the 2006 census, there were 8,048,430 inhabitants in Metropolitan Lagos. This figure was lower than anticipated and has created controversy in Nigeria. Lagos Island, the central Local Government Area and historic center of Metropolitan Lagos, had a population of 212,700 at the 2006 Census.
Authorities of Lagos State have disputed the results of the 2006 census, accusing the Nigerian National Population Commission of undercounting the population of the state. This accusation is denied by the National Population Commission. A study found that research carried out by Africapolis (the African subsidiary of e-Geopolis backed by the Agence française de développement), in addition to the cross-referencing of official figures with more scientific independent research, concluded that the 2006 census figures for Lagos State of about 9 million were valid and that the state's own assessments are inflated.
Lagos is indigenous to the Yoruba people, and the Yoruba language is widely spoken. It is, by most estimates, one of the fastest-growing cities in the world. Lagos is experiencing a population increase of about 275,000 persons per annum due to the influx of people from other regions for economic purposes. In 1999, the United Nations predicted that the city's metropolitan area, which had only about 290,000 inhabitants in 1950, would exceed 20 million by 2010 and thus become one of the ten most populous cities in the world.
Geography
Lagos is loosely classified into two main geographical areas—the "Island" and the "Mainland".
Cityscape
The city of Lagos has the tallest skyline in Nigeria. The architectural styles in Lagos are diverse, ranging from tropical and vernacular to colonial European and ultramodern buildings, or a mixture. Brazilian-style architecture brought by the creoles is evident in buildings such as Water House and Shitta Bey Mosque. Skyscrapers and most high-rise buildings are centered on the islands, while the mainland has some high-rise buildings. In recent years, the Lagos State government has renovated existing parks and green areas, with a long-term goal of expansion. Many good quality buildings are interspersed across the city.
The Island is a loose geographical term that is used to define the area of Lagos that is separated from the "Mainland" by the main channel draining the lagoon into the Atlantic Ocean, which forms Lagos Harbour. The Island is mainly a collection of islands that are separated from each other by creeks and are connected by bridges. The smaller sections of some creeks have been dredged and built over. This part of Lagos is the area where most business activities and entertainment events take place, as well as where most of the upscale residential areas are concentrated. The Local Government Areas (LGAs) that are considered to be on the Island include Lagos Island and Eti-Osa. The major upscale Island neighbourhoods within these LGAs include Ikoyi and Victoria Island. Three major bridges join the Island to the Mainland. They are the Carter Bridge, which starts from Iddo; the Eko Bridge (formerly called the Second Mainland Bridge); and the Third Mainland Bridge, which passes through densely populated mainland suburbs to the Lagos Lagoon. The Ikoyi link bridge links Ikoyi and Lekki Phase 1, both of which are part of the Island.
Construction on the Fourth Mainland Bridge will start in 2022, according to Lagos State Governor Babajide Sanwo-Olu.
Lagos Island
Lagos Island contains a central business district. This district is characterized by high-rise buildings. The Island also contains many of the city's largest wholesale marketplaces (such as the popular Idumota and Balogun Markets). It also has the National Museum of Nigeria, the Central Mosque, the Glover Memorial Hall, Christ's Church Cathedral (CMS), and the Oba's Palace (Iga Idunganran). Another major part of Lagos Island is Marina. It borders the Idumota and Balogun markets and houses major Banking institutions. Though formerly in a derelict condition, Lagos Island's Tinubu Square is a site of historical importance; it was here that the Amalgamation Ceremony that unified the North and South protectorates to form Nigeria took place in 1914.
Ikoyi
Ikoyi is situated on the eastern half of Lagos Island and joined to it by a landfill. Ikoyi is also connected to Victoria Island by Falomo bridge, which carries the main road over Five Cowrie creek. Falomo garden, a green public space which was developed by the state government in conjunction with Fidelity Bank in 2017, is located under the bridge. Ikoyi housed the headquarters of the federal government of Nigeria and other buildings owned by the government, including the old federal secretariat complex. The complex today is on reestablishment.
In Ikoyi there are military and police barracks, a top-security prison, and a federal high court of Nigeria. Ikoyi also has hotels, nightclubs, a recreational park, and one of Africa's largest golf courses. Originally a middle class neighbourhood, in recent years it has become a fashionable residential enclave for the upper middle class to the upper class. The commercial section is concentrated in the South-West.
Victoria Island
Victoria Island with its annex is situated to the south of Lagos Island and known with a zip code of 101241 as assigned by NIPOST. It has expensive real estate properties and for that reason, many new luxury condos and apartments.
Along with Ikoyi, Victoria Island occupies a major area in Lagos that boasts several shopping districts. On its seashore along the Atlantic front, there is an environmentally reconstructed Bar Beach.
Ajah/Lekki
The Lekki Peninsula shares some prestige with its Ikoyi and Victoria Island neighbours. Development has stretched the piece of land further such that the Ibeju axis, though closer to Epe (which is on the outskirts of Lagos) is almost always described as part of Lekki. The expanse of land starts from the Lekki toll gate, which was the focal stage of the famous #EndSars protest in October 2020, and ends in Ibeju-Lekki and boasts of communities slowly inching their way to suburb status such as Ajah, Awoyaya, Sangotedo, Abijo, and Eputu. There is quite a bit of place to see – the Lekki Conservation Centre; The Novare Mall; The Lekki Free Trade Zone – Dangote, Africa's richest man is building his refinery in this FTZ; Lagos Business School; Eleko Beach; Elegushi Beach; La Campagne Tropicana – a beach/tourist getaway, Pan-Atlantic University. The area has a Catholic monastery.
Iddo
Across the main channel of the lagoon from Lagos Island, there is a smaller settlement called Iddo. Iddo is also a railroad terminus and it is now situated in the Lagos Mainland Local Government Area after it was connected to the Mainland like a peninsula.
Mainland
A huge population of Lagosians also live on the Lagos Mainland, and most industries are located there. The Mainland is known for its music and nightlife, which used to be located in areas around Yaba, Ikeja, and Surulere. However, in recent years more nightclubs have sprung up on the Island, making the Island (particularly Victoria Island, Ikate, and Lekki Phase 1) the main nightlife attraction. Mainland LGAs include Surulere, Apapa, and Lagos Mainland. Metropolitan Lagos suburban LGAs include: Agege, Amuwo Odofin, Mushin, Oshodi-Isolo and Ikeja (site of Murtala Muhammed International Airport and the capital of Lagos State).
Major areas on the Mainland include Ebute Metta, Yaba and Ejigbo. Some rivers, like Badagry Creek, flow parallel to the coast for some distance before exiting through the sand bars to the sea.
Climate
Lagos experiences a tropical savanna climate (Aw) according to the Köppen climate classification, as there are three months under 60 mm or 2.4 in of rain, and annual rainfall is not nearly high enough for tropical monsoon classification. The wet season starts in May and ends in October, while the dry season starts in November and ends in April. There is also a short dry season from July to August. The wettest month is June with precipitation total 316 mm or 12.44 in, while the driest month is January with precipitation total 13 mm or 0.51 in.
Located near the equator, Lagos has only a slight seasonal temperature variation, with mean high temperatures ranging from 28 to 32 °C (82 to 90 °F). Lagos has the highest temperatures in March with a daily range from 32 to 26 °C (90 to 79 °F), and least hot temperatures in August ranging from 28 to 24 °C (82 to 75 °F), not unlike the seasons of coastal locations in the Southern Hemisphere. Summer is the coolest season, with June, July and August are the coldest and rainiest months, while spring (March - May) is the hottest season.
Climate change
A 2019 paper published in PLOS One estimated that under Representative Concentration Pathway 4.5, a "moderate" scenario of climate change where global warming reaches ~2.5–3 °C (4.5–5.4 °F) by 2100, the climate of Lagos in the year 2050 would most closely resemble the current climate of Panama City. The annual temperature would increase by 1.6 °C (2.9 °F) and the temperature of the warmest month by 1.5 °C (2.7 °F), while the temperature of the coldest month would be 2.9 °C (5.2 °F) higher. According to Climate Action Tracker, the current warming trajectory appears consistent with 2.7 °C (4.9 °F), which closely matches RCP 4.5.
Moreover, according to the 2022 IPCC Sixth Assessment Report, Lagos is one of 12 major African cities (Abidjan, Alexandria, Algiers, Cape Town, Casablanca, Dakar, Dar es Salaam, Durban, Lagos, Lomé, Luanda and Maputo) that would be the most severely affected by sea level rise. It estimates that they would collectively sustain cumulative damage of US$65 billion under RCP 4.5 and US$86.5 billion in the high-emission scenario RCP 8.5 by the year 2050. Additionally, RCP 8.5 combined with the hypothetical impact from marine ice sheet instability at high levels of warming would involve up to US$137.5 billion in damage, while the additional accounting for the "low-probability, high-damage events" may increase aggregate risks to US$187 billion for the "moderate" RCP4.5, US$206 billion for RCP8.5 and US$397 billion under the high-end ice sheet instability scenario. Since sea level rise would continue for about 10,000 years under every scenario of climate change, future costs of sea level rise would only increase, especially without adaptation measures. Sea level rise is being exacerbated by subsidence, which is occurring at up to 87 millimetres (3.4 in) per year.
Economy
The city of Lagos is a major economic focal point in Nigeria, generating around 30-35% of the country's GDP. Most commercial and financial businesses are carried out in the central business district situated on the island. This is also where most of the country's commercial banks, financial institutions, and major corporations are headquartered. Lagos is also the major information communications and telecommunications (ICT) hub of West Africa. Lagos is developing a 24-hour economy.
The globalisation of Lagos's economy is rated "beta minus" by the GaWC. This is equivalent to Manchester or Edinburgh in the UK. Lagos is thus the most "globalised" city in West and Central Africa. 5 out of 7 African tech "unicorns" operate out of Lagos (see below). Lagos is home to more tech centres than any other city in Africa.
Yves Bellinghausen from the German magazine ZEIT summarises: 'Lagos is Africa's Hollywood, Manhattan, and Silicon Valley all rolled into one.'
Financial institutions
Lagos is a major financial and banking centre. The four largest banks in West and Central Africa are headquartered in Lagos, and another nine banks in Lagos are among the 20 largest banks in the region. Zenith Bank, Access Bank, Guaranty Trust Bank and First Bank have capital of more than US$2 billion each. Banking headquarters are located on Victoria Island and Lagos Island.
The insurance industry in Nigeria is comparatively and modestly developed, with an industry turnover of around US$1 billion per year. As with the banks, the headquarters of the insurance companies are predominantly located in Lagos.
Ports
The Port of Lagos, formally known as the Lagos-Elbert Mathews Memorial Port, is Nigeria's leading port and one of the largest and busiest Ports in Africa. Due to the large urban population, Lagos is categorized as a medium-port megacity using the Southampton System for port-city classification. It is administered by the Nigerian Ports Authority. The Port of Lagos / Apapa is the oldest and largest port in the country, both in terms of land area and cargo volume handled. More than half of Nigeria's maritime trade is handled here, and the port also acts as a transhipment point for landlocked countries such as Chad and Niger. Around 1,000 ships with 5,700,000 tonnes of cargo call at the Lagos port complex annually.
Tin Can Island Port is located west of Apapa near the Lagos Port Complex. It was established in 1975.
In early 2023, the deep sea port of Lekki was commissioned 50 km east of Lagos. This thus does not belong to the urban area of Lagos but to the state of the same name.
Entertainment industry and media
Nollywood
Lagos is the centre of the West African film, music, and TV industries. The film industry in the Surulere locality ranks second or third in the world, ahead of or behind Hollywood, depending on the survey. PricewaterhouseCoopers Int. forecasts that the Nigerian entertainment industry will grow 85% to $15 billion.
