斯科舍岛弧（Scotia Arc），或名南安的列斯群岛（Southern Antilles）。是一个岛弧系统，形成斯科舍海的北、东及南面边界。岛弧包括海底山脊〔即斯科舍山脊（Scotia Ridge），又名南安的列斯（Southern Antilles）〕及众多群岛，有南奥克尼群岛（South Orkney Islands）、南格鲁吉亚岛与南桑威奇群岛、克拉克石群（Clerke Rocks）、沙格岩（Shag Rocks）及（Isla de los Estados），连系南极半岛至火地群岛及安地斯山脉诸山。

The Scotia Arc is the island arc system forming the north, east and south border of the Scotia Sea. The northern border, the North Scotia Ridge, comprises (from west to east) Isla de los Estados at the tip of Tierra del Fuego, the Burdwood, Davis, and Aurora Banks; the Shag and Clerke Rocks and South Georgia Island. The eastern border comprises the volcanic South Sandwich Islands flanked by the South Sandwich Trench. The southern border, the South Scotia Ridge, (east to west) comprises Herdman, Discovery, Bruce, Pirie, and Jane Banks; the South Orkney Islands and Elephant Island. The Bransfield Strait, finally, separates the arc from the South Shetland Islands and James Ross Island flanking the tip of the Antarctic Peninsula.
