Neko Harbour (64°50′S 62°33′W / 64.833°S 62.550°W / -64.833; -62.550) is an inlet of the Antarctic Peninsula on Andvord Bay, situated on the west coast of Graham Land.

Neko Harbour was discovered by Belgian explorer Adrien de Gerlache during the early 20th century.

The name pays tribute to the Lieutenant of the ship Felipe Fliess of the Corvette Uruguay who rescued the Swedish Antarctic Expedition headed by Otto Nordenskjöld.

Some Maintenance, repair and conservation of facilities were carried out to be used as support for scientific research.

[citation needed] Neko Harbour has been classified as an important bird and biodiversity area by BirdLife International because it supports a breeding colony of more than 250 breeding pairs of gentoo penguins that nest on the hill near the beach to avoid risk of being washed away by the large waves frequently generated from the calving of the nearby glacier.
