Lagos State (Yoruba: Ìpínlẹ̀ Èkó, Gun: Ayìmátẹ̀n Awọnlìn tọ̀n) is a state in southwestern Nigeria. Of the 36 Nigerian states, it is the second most populous state but the smallest in area. Bounded to the south by the Bight of Benin and to the west by the international border with Benin for 10 km, Lagos State borders Ogun State to the north for about 283 km, making it the only Nigerian state to border only one other state. Named for the city of Lagos—the most populous city in Africa—the state was formed from the Western Region and the former Federal Capital Territory on 27 May 1967.

Geographically, Lagos State is dominated by bodies of water with nearly a quarter of the state's area being bodies of water. The largest of these bodies are the Lagos and Lekki lagoons in the state's interior with the Ogun and Osun rivers flowing into them. Many other rivers and creeks flow throughout the state and serve as vital means of transportation for people and goods. On land, non-urbanized areas are within the tropical Nigerian lowland forests ecoregion with natural areas containing threatened populations of mona monkey, tree pangolin, and hooded vulture along with a transitory population of African bush elephants. Offshore, the state is also biodiverse as there are large fish populations along with African manatees and crocodiles.

Lagos State has been inhabited for years by various indigenous ethnic groups, primarily the majority Yoruba people that live throughout the state but also the Ewe and Ogu peoples in the far west. As a result of migration since the nineteenth century, Lagos State also has large populations of non-native Nigerian ethnic groups with Edo, Fulani, Hausa, Igbo, Ijaw, Ibibio, Efik, and Nupe peoples among other Nigerian groups. There are also groups from outside of Nigeria's modern borders with the Saro (Sierra Leonean) and Amaro (Brazilian) groups being descendants of formerly enslaved people that returned to Africa in the 1800s with a longstanding Middle Eastern Nigerian community (mainly Syrian and Lebanese Nigerians) also forming a significant part of Lagos' population along with recent immigrants from Benin, China, Ghana, India, Togo, and the United Kingdom. Religiously, the state is also diverse, as there is a sizable number of Christian, Muslim and traditional ethnic religions.

In the pre-colonial period, the area that is now Lagos State was mainly fishing villages and ports that at various points were controlled by states including the Oyo Empire and Benin Kingdom until the early 1800s when the city of Lagos had developed into a major kingdom of its own right. In 1850, the British successfully attacked the kingdom in the Bombardment of Lagos before installing an ally as Oba and signing a treaty that established Lagos as being under British protection. Ten years later, the forced Lagos Treaty of Cession led to the formal establishment of the Lagos Colony. In 1906, the colony was incorporated into the new Southern Nigeria Protectorate which merged into British Nigeria in 1914 with the city of Lagos as its capital. Upon independence in 1960, Lagos remained as the capital with much of the city forming the Federal Capital Territory while the rest of modern-day Lagos State was a part of the Western Region until 1967 when the region was split and the area became Lagos State.

Economically, Lagos State is one of the fastest-growing urban areas in the world. It contains the most populous city in Nigeria and one of the most important states in the country, a major financial centre and has one of the largest economies in Africa with a gross domestic product of $84 billion comparable with Ghana's $75 billion, Angola's $70 billion, and Ethiopia's $93 billion. Lagos State is also a key culture, education, and transportation hub for Nigeria and Sub-Saharan Africa. Additionally, the state also has the highest literacy rate in Nigeria. It is known for its vibrant culture, bustling markets, and significant economic activities. Despite overcrowding and chronic debilitating traffic, Lagos State has the highest Human Development Index in Nigeria and numerous developmental projects.

Before the Portuguese name of Lagos had been adopted, Lagos' initial name was Eko which referred mainly to the Island. The first to settle in Eko were the Aworis in the 15th century and the Binis in the 16th century. The Aworis were conquered by the Benin Empire. The Awori hunters and fishermen had originally come from Ile-Ife to the coast.

It was in 1760 that the name Lagos was adopted by the Portuguese. Naming it after a city in Southern Portugal which was used as port for slave trade. In 1861, Oba Docemo was the one who signed the treaty making Lagos a British colony.

Lagos State was created on 27 May 1967 according to the State Creation and Transitional Provisions Decree No. 14 of 1967, which restructured Nigeria into a federation of 12 states. Before the issuance of this Decree, Lagos city, which was the country's capital had been administered directly by the Federal Government through the Federal Ministry of Lagos Affairs. However, Ikeja, Agege, Mushin, Ikorodu, Epe, Surulere, and Badagry were administered by the then Western Region Government. Lagos, the city, along with these other towns were captured to create the state of Lagos, with the state becoming fully recognized as a semi-autonomous administrative division on 11 April 1968. Lagos served the dual role of being the State and Federal Capital until 1976 when the capital of the state was moved to Ikeja. After the full establishment of the Federal Capital Territory, based on the recommendation of the Akinola Àgùdà–led committee set up by General Murtala Muhammed to review the need for a new capital for Nigeria in 1975. The seat of the Federal Government was formally relocated to Abuja on 12 December 1991. Nevertheless, Lagos remains the financial centre of the country, and even grew to become the most populous city in the state and the country.

Lagos is the most populous city in Lagos State, Nigeria as a whole, and the continent of Africa. The conurbation is one of the most populous in the world. Lagos is a port which originated on islands separated by creeks, such as Lagos Island, fringing the southwest mouth of Lagos Lagoon while protected from the Atlantic Ocean by barrier islands and long sand spits such as Bar Beach, which stretch up to 100 kilometres (62 miles) east and west of the mouth. The metropolitan area of Lagos includes Ikeja (which is the capital of Lagos State) and Agege and Mushin.

Ikeja is the state capital of Lagos State. Ikeja is a planned residential and commercial town with shopping malls, pharmacies and government reserved areas. The Murtala Mohammed International Airport is in Ikeja. Ikeja is also home to Fela Kuti's African Shrine, Late Chief Gani Fawehinmi house and Lagbaja's Motherland. It also has the largest shopping center on the mainland.

Lekki is a city in the south eastern part of the state. It is a naturally formed peninsula, it is still largely under construction. As of 2015, only phase 1 of the project had been completed, with phase 2 nearing completion. The peninsula is approximately 70 to 80 km long, with an average width of 10 km. Lekki currently houses several estates, gated residential developments, agricultural farmlands, areas allocated for a Free Trade Zone, an airport, and a sea port under construction. The proposed land use master plan for the Lekki envisages the Peninsula as a "Blue-Green Environment City", expected to accommodate over 3.4 million residential population and an additional non-residential population of at least 1.9 million.

Ikorodu is a city located north-east of the state along the Lagos Lagoon. It shares a boundary with Ogun State. As of the 2006 Census, Ikorodu had a population of 535,619. It is the third largest city in the south-west after Ibadan and Lagos and the 12th largest city in Nigeria. In 2022, it had an estimated population of 1,041,066. The population of the city currently grows at 5.26% annually, and it is projected to reach 1.7 million by 2035.

Eko Atlantic is a planned city being constructed on land reclaimed from the Atlantic Ocean. It is located on the former Lagos' Bar Beach. Upon completion, the new island which is still under development is anticipating at least 250,000 residents and a daily flow of at least 150,000 commuters. The development will also have a positive environmental impact; its purpose is to stop the erosion of the Lagos coastline. The Eko Atlantic City project received global recognition in 2009, as the Lagos State government and its private sector partners on the Project, South Energyx, received the Clinton Global Initiative Commitment Certificate.

Badagry is a coastal town in the state. It is situated between Metropolitan Lagos, and the border of the Republic of Benin at Seme. As of the preliminary 2006 census results, the municipality had a population of 241,093. The area is led by a traditional king, Akran De Wheno Aholu Menu – Toyi 1, who is also the permanent vice-chairman of obas and chiefs in Lagos State. It is known to hold the country's oldest storey building. Badagry is home to the Ewe and Egun people who are predominantly fishermen.

Epe is a town located on the north side of the Lekki Lagoon. It is popular for the fishing activities attributed to the city. Per the 2006 Census the population of Epe was 181,409.

Epe is widely regarded as Lagos's fishing capital. Fishing is the main occupation of the people here, so it is no surprise that a sculpture of two giant fishes, erected at the Lekki-Epe T-Junction, welcomes you to Epe. The Epe Fish Market is regarded as Lagos's largest seafood market.

Lagos State houses headquarters of most conglomerates and commercial banks in Nigeria. The state has the lowest incidence of extreme poverty (around 1.3% of the population against a national average of 31%) of all states in Nigeria, according to World Bank data from 2018. Despite that, slums and poverty are a major issue in the Lagos area.

Its total generated revenue in 2017 was around ₦334 billion (equivalent to US$920 million), growing by 10.43% compared to 2016. By the first half of 2021, the State's internally generated revenue (IGR) alone stood at over ₦267 billion.

Lekki Free Trade Zone (Lekki FTZ) is a free zone situated at the eastern part of Lekki, which covers a total area of about 155 square kilometres. The first phase of the zone has an area of 30 square kilometres, with about 27 square kilometres for urban construction purposes, which would accommodate a total resident population of 120,000. According to the Master Plan, the free zone will be developed into a new modern city within a city with integration of industries, commerce and business, real estate development, warehousing and logistics, tourism, and entertainment.

The following mineral resources are found in Lagos State:

Lagos has a Tropical wet and dry or savanna climate. The city's yearly temperature is 28.67 °C (83.61 °F) and it is -0.79% lower than Nigeria's averages. Lagos typically receives about 132.01 millimeters (5.2 inches) of precipitation and has 193.63 rainy days (53.05% of the time) annually.

• Water Pollution In Lagos, water contamination is a significant issue. Serious health concerns have been raised as a result of the unchecked discharge of raw sewage, sediment-carrying runoff, and effluents into the Lagoon system. People are suffering from deadly waterborne illnesses like cholera and diarrhea as a result. The number of Lagos inhabitants who have access to formal clean water is pitifully small, with most of them reliant on the unofficial sector made up of wells. Lagos has a tropical environment with over 2,000 millimeters of annual rainfall, is surrounded by water, however much of the water is unsafe to drink. The bulk of Lagos inhabitants rely on the unofficial sector, which consists of wells, boreholes, rivers, and rains, as there is very little access to formal clean water. The state's daily demand in 2016 was
• Air pollution
• Waste
• Traffic congestion
• Noise pollution

The Fourth Mainland Bridge is a 38 km long bridge project by the Lagos State Government, connecting Lagos Island by way of Langbasa(Lekki) and Baiyeku(Ikorodu) across the Lagos Lagoon to Itamaga, in Ikorodu. The bridge is a 2 x 4 lane carriageway cross-sectional road with permission for BRT Lane and future road contraction. It is expected to become the second longest bridge in Africa, featuring 3 toll plazas, 9 interchanges, 4.5 km Lagoon Bridge and an eco-friendly environment amongst other added features. In April 2021 there were 6 bidders for the US$2.5 billion project. By December the preferred bidder would be known.

In January 2022 the Lagos State Governor, Babajide Sanwo-Olu, reiterated the plan by the state government to commence the construction on the Opebi-Mende link bridge and the 38-kilometre 4th mainland bridge: "Construction work on the 38km 4th Mainland Bridge — which will be the longest in Africa — and the Opebi-Mende link bridge will commence this year."
