威廉群岛是南极洲的群岛，位于南极半岛西岸，该群岛在1873年至1874年被德国采险家发现，英国、阿根廷和智利在南极条约体系下搁置对该群岛的领土主权要求。

The Wilhelm Archipelago (65°8′S 64°20′W / 65.133°S 64.333°W / -65.133; -64.333) is an island archipelago off the west coast of the Antarctic Peninsula in Antarctica.

Wilhelm Archipelago consists of numerous islands, the largest of which are Booth Island and Hovgaard Island. The archipelago extends from Bismarck Strait southwest to Lumus Rock, off the west coast of Graham Land. It was discovered by a German expedition under Eduard Dallmann, 1873–74. He named them for Wilhelm I, then German Emperor and King of Prussia.
