The history of the Nigerian ports Authority dates backs to the time of the slave trade or the colonial masters when the ports/ Territorial waters. In 1862, a department known as marine department then had regional headquarters established and located at the following places.

(a) Lagos colony marine – 1862 – Lagos

(b) Southern Nigeria marine – 1993 – Calabar but later transferred to Akasa in 1902

(c) Northern Nigeria marine-1900-Lokoja in 1960, two of the Regional Head Quarters, i.e. Lagos Colony marine were merged to become Southern Nigerian marine.

In 1908, a separate Government department know as port department was formed to take charge of civil Engineering works in Lagos and Port Harcourt ports. This was followed with the creation of the Nigerian marine in 1914 with two Regional Head Quarters as founding members.
