Lagos State (Yoruba: Ìpínlẹ̀ Èkó) is a state in southwestern Nigeria. Of the 36 states, it is both the most populous and smallest in area. Bounded to the south by the Bight of Benin and to the west by the international border with Benin Republic, Lagos State borders Ogun State to the east and north 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.
