Teesport is a large sea port located in the unitary authority of Redcar and Cleveland, in the ceremonial county of North Yorkshire, Northern England.

Owned by PD Ports, it is located approximately 1 mile (2 km) inland from the North Sea and 4 miles (6 km) east of Middlesbrough on the River Tees.^[1] Teesport is currently the third largest port in the United Kingdom, and amongst the ten biggest in Western Europe, handling over 56 million tonnes of domestic and international cargo per year.^[2]

The port covers an area of 200 hectares (490 acres) of land alongside the southern bank of the River Tees. Presently handling over 6,000 ships and 56 million tonnes of cargo per annum, Teesport is mostly associated with the handling of steel, petrochemical, manufacturing, engineering and retail.^[3] Teesport is the logistical hub for the commodity chemical and steel companies that are members of the Northeast of England Process Industry Cluster (NEPIC).

The first developed facility on the current Teesport location was a Royal Navy depot during World War I. This allowed the allocated six British E-class submarines to operate further into the North Sea during their defence, attack and mine laying operations against the Imperial German Navy.^[10] At this time, commercial port facilities were still handled at Middlesbrough Docks, located further upstream.

In the 1920s, Eston Urban District Council decided to turn the 13 former dormitories of the former Royal Navy facility into 38 small houses, within a community called Teesport. By the start of World War II, of the original 130 residents that came when the community was developed, only 3 remained. This was because in 1934, the joint owners of the land on which the community was built – riverside and shoreline Swan Hunter & Wigham Richardson; landside Dorman Long – had written to the council to seek assurances that they would not let any more houses within the community, so allowing the land owners to take back possession and be allowed to develop their businesses on the land. After the war, due to over-crowding around the original Port Darlington and Middlesbrough Docks facility, both companies developed industrial facilities on the land, and sub-leased some land to other commercial operations.^[10]

Between 1965 and 1968, three oil refineries were developed close to Teesport, thanks to the Phillips Petroleum's development of the Ekofisk oil field in the North Sea.^[11] The first two were jointly developed and operated by Phillips and ICI on the north shore of the River Tees at the North Tees Works, just south of Greatham Creek. After processing this facility fed cyclohexane, benzene, toluene and xylene to ICI's chemical plants at Billingham and Wilton.^[11] The third refinery was developed in 1968 by Shell Oil on the south shore within Teesport.^[11] This facility was served by what became known as Tees Dock, with the whole docks facility designed around Panamax scale ships.^[2] In 1980, with the discovery of North Sea gas, a 220 miles (350 km) pipeline was installed between Ekofisk and Seal Sands on the north shore.^[11] Although the Shell refinery was mothballed in 1989 and later closed, and the north shore facility of Petroplus closed in 2010,^[12] as a result of the pipeline petrochemicals traffic still today represents about 50% of the cargo through Teesport, around 26 million tonnes a year.^[2]

In 1992 the Port Authority of Tees and Hartlepool was privatised, with the original three buyers subsequently reduced to a single owner, Powell Duffryn Plc, in 1995. With traffic out-scaling the port's handling and ship-scale facilities, PD Ports then developed TCT2 in 2002 specifically as a deep-sea cargo quay on top of the site that used to be the original Tees Dock.^[2]

In March 2021, Teesport became the UK's largest Freeport.^[13][14]
