Flats in Obalende, Lagos Island, Lagos

Lagos Island is a Local Government Area (LGA) located in the central part of the city of Lagos, Lagos state, Nigeria. It is part of the Lagos Division. As of the preliminary 2006 Nigerian census, the LGA had a population of 209,437 in an area of 8.7 km². The LGA only covers the western half of Lagos Island; the eastern half is under the jurisdiction of the LGA of Eti-Osa. The Island was home to the Yoruba fishing village of Eko, which grew into the modern city of Lagos. The city has now spread out to cover the neighboring islands as well as the adjoining mainland.

There are three bridges which connect Lagos Island to the mainland, and they cross Lagos Lagoon to the district of Ebute Metta. Most Nigerian banks' head offices are located on Lagos Island. For instance, First Bank of Nigeria is one of the Nigerian Banks with its head office in Marina, Lagos Island.
