亚历山大群岛（Alexander Archipelago）是美国阿拉斯加州东南部海岸外的一个群岛，由超过1100个岛屿组成。各岛与大陆间隔着著名的内湾航道相望，覆盖着浓密的森林，旅游业、林业和渔业是当地经济的支柱。

该群岛得名自俄罗斯探险家亚历山大·巴拉诺夫。1741年，俄罗斯人首先考察了该群岛，并创建殖民据点，1867年，该群岛随同整个阿拉斯加被出售与美国。

The Alexander Archipelago is a 300 miles (500 km) long archipelago, or group of islands, of North America off the southeastern coast of Alaska. It contains about 1,100 islands, which are the tops of the submerged coastal mountains that rise steeply from the Pacific Ocean. Deep channels and fjords separate the islands and cut them off from the mainland. The northern part of the Inside Passage is sheltered by the islands as it winds its way among them.
