Container terminal in the context of Garden City, Georgia

The Port of Singapore is a collection of facilities and terminals that conduct maritime trade and handle Singapore's harbours and shipping. Since 2015, it has been ranked as the world's top maritime capital. Currently, it is ranked as the world's second-busiest port in terms of total shipping tonnage, while also transshipping a fifth of the world's shipping containers, and half of the world's annual crude oil supplies, alongside being ranked as the world's busiest transshipment port. Furthermore, it was also ranked as the world's busiest port in terms of total cargo tonnage handled until 2010, when it was surpassed by the Port of Shanghai.

Due to the city-state's strategic location, Singapore has served as a significant entrepôt and trading post on an international level for at least two centuries. During the contemporary era, its ports have been regarded not merely as an economic boon for the country, but as vitally important for the country's economic development since Singapore lacks land and natural resources. Additionally, the port is regarded as particularly important for importing natural resources, and then later re-exporting products after they have been domestically refined and shaped in some manner, for example, wafer fabrication or oil refining to generate value-added revenue. The Port of Singapore is also the world's largest bunkering port. Moreover, the majority of ships that pass between the Indian Ocean and the Pacific Ocean go through the Singapore Strait. The Straits of Johor on the country's north are impassable for ships due to the Johor-Singapore Causeway, built in 1923, which links the town of Woodlands, Singapore, to the city of Johor Bahru in Malaysia.

This article lists the world's busiest container ports (ports with container terminals that specialize in handling goods transported in intermodal shipping containers), by total number of twenty-foot equivalent units (TEUs) transported through the port. The table lists volume in thousands of TEU per year. The vast majority of containers moved by large, ocean-faring container ships are 20-foot (1 TEU) and 40-foot (2 TEU) ISO-standard shipping containers, with 40-foot units outnumbering 20-foot units to such an extent that the actual number of containers moved is between 55%–60% of the number of TEUs counted.

The latest ranking reflected the figures for the year 2025, as published in the Lloyds List Top 100 and World Shipping Council (2025 figures), unless otherwise indicated.

The Maasvlakte Rotterdam (or simply the Maasvlakte; Dutch pronunciation: [ˈmaːsflɑktə]) is a massive man-made westward extension of the Europoort port and industrial facility within the Port of Rotterdam. Situated in the municipality of Rotterdam in the Netherlands, the Maasvlakte is built on land reclaimed from the North Sea.

The Port of Durban, commonly called Durban Harbour, is the largest and busiest shipping terminal in sub-Saharan Africa. It handles up to 31.4 million tons of cargo each year. It is the fourth largest container terminal in the Southern Hemisphere, handling approximately 4.5 million TEU in 2019.

A container crane (also container handling gantry crane or ship-to-shore crane) is a type of large dockside gantry crane found at container terminals for loading and unloading intermodal containers from container ships.

Container cranes consist of a supporting framework that can traverse the length of a quay or yard on a rail track. Instead of a hook, they are equipped with a specialized handling tool called a spreader. The spreader can be lowered on top of a container and locks onto the container's four locking points ("corner castings") using a twistlock mechanism. Cranes normally transport a single container at once, but some newer cranes have the capability to pick up two to four 20-foot containers at once.

Seaforth Dock (also known as the Royal Seaforth Dock) is a purpose-built dock and container terminal, on the River Mersey, England, at Seaforth, to the north of Liverpool. As part of the Port of Liverpool and Liverpool Freeport, it is operated by the Mersey Docks and Harbour Company. Situated at the northern end of the dock system, it is connected to Gladstone Dock to the south, which via its lock entrance provides maritime access to Seaforth Dock from the river.

Haydarpaşa station (Turkish: Haydarpaşa Garı) is a railway station in Istanbul, that was, until 2012 the main city terminal for trains travelling to and from the Anatolian side of Turkey. It used to be Turkey's busiest railway station. (Its counterpart on the European side of the city was Sirkeci station which served train services to and from the Thracian side of the country.) The station building still houses the headquarters for District 1 of the State Railways but since a fire in 2010 the station has not been in use and its future remains uncertain.

Haydarpaşa stands on an embankment over the Bosphorus just south of the Port of Haydarpaşa (one of the main container terminals in Turkey) and is slightly north of busy Kadıköy. Until the rail service was suspended, ferry services connected it to Eminönü, Karaköy and Kadıköy.
