马歇尔群岛（英语：Marshall Archipelago）为位在南极洲苏兹贝格湾海域上的群岛，由众多冰雪覆盖的岛屿所组成。这些岛屿由海军上将理查·E·伯德所率领的伯德南极探险队（Byrd Antarctic Expedition，1928年－1930年；1933年－1935年）和美国南极服务（United States Antarctic Service，1939年－1941年）发现 。美国地质调查局依据调查以及美国海军之航空照（1959年－1965年）将此群岛绘入至地图中。因五星上将乔治·卡特莱特·马歇尔于1933年至1935年间以个人身分资助并且提供咨询援助予伯德探险队，理查·E·伯德将此群岛命名为马歇尔。

The Marshall Archipelago is an extensive group of large ice-covered islands within the Sulzberger Ice Shelf off Antarctica. Several of the islands were discovered and plotted by the Byrd Antarctic Expeditions (1928–30 and 1933–35) and by the United States Antarctic Service (1939–41), all led by Admiral Richard E. Byrd. The full extent of the archipelago was mapped by the United States Geological Survey from surveys and U.S. Navy air photos (1959–65). The name was proposed by Admiral Byrd for General of the Army George C. Marshall, who made financial contributions as a private individual and also, on the same basis, provided advisory assistance to the Byrd expedition of 1933–35.
