Antarctic Haven (Danish: Antarctichavn)[1] is a bay in King Christian X Land, Northeastern Greenland.

This natural harbour was named "Antarctics Hamn" by Swedish Arctic explorer Alfred Gabriel Nathorst after his ship Antarctic, which anchored there on 20 August 1899 during the Swedish Greenland Expedition in search of survivors of S. A. Andrée's Arctic balloon expedition of 1897.

[3] In the southern corner of the head of the bay there is a Norwegian hunting hut that originally had been known as "Karlsbak Station".

[1] The historical Norwegian Antarctic Haven Station was restored in the summer 2001 by the Nanok East Greenland Fishing Company.

[7] This northeast-facing bay is located in NE Scoresby Land, at the southern end of the King Oscar Fjord, in the Davy Sound area.
