Ocean Harbour (Spanish: Puerto Nueva Fortuna) is a deeply indented bay on Barff Peninsula on the north coast of South Georgia which is entered 1.5 miles (2.4 km) west-northwest of Tijuca point. It was a whaling station between 1909 and 1920. At one point, South Georgia was the whaling capital of the world.
The names New Fortune Bay and Neufortuna Bay, probably for the whaling catcher Fortuna (owned by the Norwegian-Argentine whaling company Pesca), were used for this site in 1922 by Filchner, following the German Antarctic Expedition, 1911–12. In 1951–52 the island was surveyed by the South Georgia Survey who reported the site was known to whalers and sealers as Ocean Harbour, a name derived from the Ocean Whaling Co. which at one time had a station there. The name Ocean Harbour is approved for this feature on the basis of local usage, and also to avoid confusion of the name New Fortuna Bay with Fortuna Bay, only 22 miles (35 km) to the northwest.
