Lagos Colony was a British colonial possession centred on the port of Lagos in what is now southern Nigeria. Lagos was annexed on 6 August 1861 under the threat of force by Commander Beddingfield of HMS Prometheus who was accompanied by the Acting British Consul, William McCoskry. Oba Dosunmu of Lagos (spelled "Docemo" in British documents) resisted the cession for 11 days while facing the threat of violence on Lagos and its people, but capitulated and signed the Lagos Treaty of Cession. Lagos was declared a colony on 5 March 1862. By 1872, Lagos was a cosmopolitan trading center with a population over 60,000. In the aftermath of prolonged wars between the mainland Yoruba states, the colony established a protectorate over most of Yorubaland between 1890 and 1897. The protectorate was incorporated into the new Southern Nigeria Protectorate in February 1906, and Lagos became the capital of the Protectorate of Nigeria in January 1914. Since then, Lagos has grown to become the largest city in West Africa, with an estimated metropolitan population of over 9,000,000 as of 2011.

The following is a timeline of the history of the metropolis of Lagos, Nigeria.

Southern Nigeria was a British protectorate in the coastal areas of modern-day Nigeria formed in 1900 from the union of the Niger Coast Protectorate with territories chartered by the Royal Niger Company below Lokoja on the Niger River.The Lagos colony was later added in 1906, and the territory was officially renamed the Colony and Protectorate of Southern Nigeria. In 1914, Southern Nigeria was joined with Northern Nigeria Protectorate to form the single colony of Nigeria. The unification was done for economic reasons rather than political—Northern Nigeria Protectorate had a budget deficit; and the colonial administration sought to use the budget surpluses in Southern Nigeria to offset this deficit.Sir Frederick Lugard, who took office as governor of both protectorates in 1912, was responsible for overseeing the unification, and he became the first governor of the newly united territory. Lugard established several central institutions to anchor the evolving unified structure. A Central Secretariat was instituted at Lagos, which was the seat of government, and the Nigerian Council (later the Legislative Council), was founded to provide a forum for representatives drawn from the provinces. Certain services were integrated across the Northern and Southern Provinces because of their national significance—military, treasury, audit, posts and telegraphs, railways, survey, medical services, judicial and legal departments—and brought under the control of the Central Secretariat in Lagos.The process of unification was undermined by the persistence of different regional perspectives on governance between the Northern and Southern Provinces, and by Nigerian nationalists in Lagos. While southern colonial administrators welcomed amalgamation as an opportunity for imperial expansion, their counterparts in the Northern Province believed that it was injurious to the interests of the areas they administered because of their relative backwardness and that it was their duty to resist the advance of southern influences and culture into the north. Southerners, on their part, were not eager to embrace the extension of legislation originally meant for the north to the south.
