port city, Eastern Cape province, South Africa. It lies at the mouth of the Buffalo River along the Indian Ocean.

Buffalo Harbour, first visited by the British in 1836 and named Port Rex, was used as a supply base during the seventh Cape Frontier War (1846). The next year, Fort Glamorgan (now a prison) was built, and the site was annexed to Cape Colony as the Port of East London. It prospered after the arrival of German settlers in the late 1850s, becoming a town in 1873 and a city in 1914.

The city has beach resort facilities. Built mainly on the east bank of the river, it has wide straight streets and gardens. It is a terminus of the South African Railways line servicing the Free State province goldfields. There is a considerable fishing industry, and manufactures are diversified. The East London Museum (established 1921) has a noteworthy natural history collection. East London is administered by the Buffalo city municipality. Pop. (2001) 135,560.
