Antarctic Bay (Danish: Antarctic Bugt) is a bay in the Greenland Sea coast of the Crown Prince Christian Land peninsula, King Frederick VIII Land, Northeastern Greenland.

The bay was named by the 1906-1908 Denmark expedition after Alfred Gabriel Nathorst's ship Antarctic.

It lies between Amdrup Land to the west and the Flade Isblink ice cap to the north.

It is a fairly wide bay, with the Nordostrundingen about 50 km (31 mi) to the northeast of its unnamed northeastern point.

[3] Kilen lies just a few km north of the ice-covered head and northeastern shore of the bay.
