Lekki is a city in Lagos State, Nigeria. It is located to the south-east of Lagos city. Lekki is a naturally formed peninsula, adjoining to its west Victoria Island and Ikoyi districts of Lagos, with the Atlantic Ocean to its south, Lagos Lagoon to the north, and Lekki Lagoon to its east; however, the city's southeast, which ends around the western edge of Refuge Island, adjoins the eastern part of Ibeju-Lekki LGA.
The city 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.
