The Port of Lagos is Nigeria’s main seaport, a group of terminals on Lagos Harbour in south-western Nigeria, where Lagos Lagoon drains into the Gulf of Guinea through a single dredged channel. Its core is the Lagos Port Complex at Apapa, whose first deep-water berths opened in 1926, backed by Tin Can Island Port (opened 1977) just to the west and, since April 2023, the Lekki Deep Sea Port 50 km to the east. Apapa alone handles more than half of Nigeria’s maritime trade, and Lagos as a whole handles about 88% of the country’s exports. The port matters because Nigeria is Africa’s most populous country and more than half of its maritime trade still passes through the quays inside this one lagoon mouth, whose sandbar, shallow water and crowded shoreline have decided where every terminal went.
A Lagoon Behind a Sandbar: the Setting of Lagos Harbour
The city takes its name from its water. Lagos comes from the Portuguese word for “lakes”, and the lake in question is Lagos Lagoon, a shallow body more than 50 km long and 3 to 13 km wide that collects the discharge of the Ogun and Osun rivers. A long sand spit and a chain of barrier islands, including the strip now occupied by Victoria Island and Bar Beach, separate the lagoon from the Atlantic, stretching up to 100 km east and west of the harbour mouth. To the north-east, narrow channels link it to Lekki Lagoon and, through a belt of creeks and swamps, as far east as Sapele, some 250 km away.
All of that water reaches the sea through one gap. Lagos Harbour is the main channel through the heart of the city, between 0.5 and 1 km wide and about 10 km long. Lagos Island, the original town, sits where the channel meets the lagoon, bounded by the Commodore Channel on one side and Five Cowrie Creek on the other. Opposite it, on the mainland shore, a broad western branch of the harbour opens towards Apapa and continues into Badagry Creek. That branch is the reason the port is where it is: it offers sheltered water on the mainland shore, directly across from the old trading town, and Wikipedia’s Lagos Lagoon article names it as the site of the city’s principal ocean port.
The same geography that sheltered ships also kept them out. The lagoon itself is too shallow for ocean-going vessels and is used only by barges and smaller boats, and for most of the nineteenth century a natural sandbar and strong tides across the harbour mouth made Lagos a dangerous entry. Cargo bound for Lagos was sometimes diverted to the calmer entrance at Forcados in the Niger Delta, and smaller ships lightered goods over the bar.
Cutting the Bar: the Harbour Works Finished in 1913
What turned a lagoon anchorage into a port was a single engineering decision. In 1906 the colonial government budgeted a large sum to dredge Lagos harbour and build two stone moles, breakwaters that confine the tidal current so that it scours its own channel through the bar. The works were completed in 1913, and from then on ocean-going ships could enter the harbour directly. Nigeria was formally amalgamated a year later, in a ceremony at Tinubu Square on Lagos Island, and the new colony had a gateway to match.
The second decision followed the railway. The Western railway from the interior had its terminus at Lagos, and planners chose the Apapa shore as the place where trains and ships would meet. In 1919 a 180-foot wharf was extended to Apapa. By 1926 four deep-water berths totalling 1,800 feet were complete there, and Apapa quickly overtook the older wharves at Iddo and at the Customs wharf on Lagos Island. Agricultural exports from the provinces of western and northern Nigeria now came down the line and out through Apapa, which by the late 1920s was the country’s busiest port for agricultural exports.
Apapa Quays: from a 180-Foot Wharf to 1.9 Million Tonnes in 1966
The figures recorded for Apapa show how quickly the new site filled. Between 1928 and 1929 the wharf handled 201,307 tonnes of export goods. A decade later, in 1937–38, it handled about 370,000 tonnes. By 1953 the figure was close to 700,000 tonnes. After the Nigerian Ports Authority was set up in 1955, it added six berths in an extension completed in 1961, and a second extension during the first national development plan of 1962 to 1968. By the end of 1966 Apapa handled 1.9 million tonnes of cargo, from a wharf area of about 100 hectares able to work twenty ships at once.
The mainland site had room to grow sideways along the creek. A third extension along Badagry Creek was completed in 1979, with facilities for bulk cement and grain. Today the Lagos Port Complex covers more than 80 hectares and includes the Apapa quays, the Third Apapa Wharf Extension, a dockyard, a petroleum wharf, a bulk vegetable oil wharf, the Ijora wharf, where coal is handled at a 150 m facility, and the Kirikiri Lighter Terminal. Its container terminal, run by APM Terminals since the 2005 concession, covers 55 hectares with a quay 1,005 m long and an annual capacity of over 1,000,000 TEU (twenty-foot equivalent units).
Tin Can Island and the Cement Armada of 1975
The shortage of quay space became a national crisis in 1974 and 1975. Nigeria’s Ministry of Defence ordered cement for a barracks programme and issued delivery letters for 16 million tonnes within a year, although the country needed under 3 million tonnes annually; other agencies ordered about 4 million tonnes more. Around 400 cement ships arrived at Lagos between late 1974 and 1975, and turnaround times for hundreds of vessels stretched to 180 days. The episode became known as the cement armada.
The answer was to use the next piece of shoreline. Tin Can Island, about seven kilometres due west of central Lagos across the harbour, was developed from 1976 and opened in 1977, with roll-on/roll-off berths; the government spent over 190 million naira completing it. In 2006 the old RoRo port and Tin Can Island were merged into one complex. It now covers 79 hectares with 12 berths totalling 1,358 m, but water depths of only 7 to 11 m limit it to ships of about 260 m in length. Its newer container terminal has 770 m of berths at 13 m depth and was designed for 650,000 TEU a year, and a grain terminal with 28,000-tonne silos takes in about 4,000 tonnes of wheat, maize and malt a day.
Where the Lagoon Runs Out of Depth: Why Lekki Was Built 50 km East
Every terminal inside the harbour inherits the harbour’s limits. Ships must pass the bar and navigate a narrow channel lined by the city, and the berths at Apapa and Tin Can were built for the vessels of the twentieth century. The world’s largest container ships, now more than 61 m wide, are far too big for them. The solution was to leave the lagoon altogether and build on the open coast of the Lekki Peninsula, inside the Lagos Free Zone.
Lekki had to create the shelter that the lagoon had provided for free. A main breakwater 1.5 km long protects the basin, and an 11 km approach channel leads to a 600 m turning circle sized for ships of up to 16,000 TEU. The container terminal has an initial draft of 14 m, with room to dredge to 16.5 m, and a capacity of about 2.5 million TEU a year, more than Apapa and Tin Can’s container terminals combined. It was the first port in Nigeria with ship-to-shore gantry cranes. The first commercial ship, the CMA CGM Mozart, docked on 22 January 2023, and full commercial operations began that April.
Trucks, Subsidence and Sea Level: What the Site Costs Lagos Now
When the Apapa berths opened in 1926, planners expected most cargo to move by rail. Instead, trucks became the main link to the interior, and the roads into Apapa, squeezed between the creek and dense neighbourhoods, became notorious for gridlock as lorries parked along the roadside waiting for the gates. The port’s lagoon-side position means there is no spare land to widen them. Lekki sits outside the old city, yet it too needs better road and rail links; the Lagos State governor promised six-lane highways at its handover in October 2022, and in December 2022 the port company announced it would fund an 800 million US dollar railway to Ijebu-Ode. In 2025 a decision was taken to spend one billion US dollars modernising Apapa and Tin Can.
The city around the port has changed out of all recognition. The 2006 census counted 8,048,430 people in Metropolitan Lagos, a figure the state government disputed; estimates in November 2025 put the city at 17 to 21 million. Much of that growth has pressed onto the lagoon edge, and the lagoon itself suffers. Large volumes of wastewater are released into it daily, and industrial waste arrives via the Ogun and Osun rivers, and WHO and UN Environment assessments cited on Wikipedia rank it among the most polluted ecosystems in Africa.
The low, sandy setting that made the harbour possible also makes it vulnerable. The 2022 IPCC Sixth Assessment Report lists Lagos among twelve African cities expected to be most severely affected by sea-level rise, and the weight of high buildings on soft ground has already caused land subsidence in the city. Barrier islands, sand spits and quays reclaimed from creek margins are exactly the ground most exposed. The port’s future is therefore tied to the same coastline that created it, a point developed further in our guide to the geography of Lagos.
For the national picture, the port sits at the centre of Nigeria’s economy, carrying the refined fuel, grain, vehicles and manufactured goods that the country imports, while its container volumes remain far below those of the giants listed in our ranking of the world’s busiest ports.
