莫雷纳湾是南极洲的海湾，位于南格鲁吉亚岛，处于昆伯兰东湾西翼，全长6公里，由瑞典探险家奥托·努登舍尔德率领的探险队绘入地图。

Moraine Fjord is an inlet 3.5 nautical miles (6 km) long with a reef (a terminal moraine) extending across its entrance, forming the west head of Cumberland East Bay, South Georgia. It was charted by the Swedish Antarctic Expedition under Otto Nordenskjöld, 1901–04, who so named it because of the large glacial moraine at its entrance.
