德朗盖岛是冰岛的火山岛，位于大西洋斯卡加峡湾海域，面积0.2平方公里，最高点海拔高度180米，该岛是海雀、海鹦等鸟类的栖息地，岛上无人居住。

Drangey or Drang Isle, with its steep sea cliffs, towers majestically in the midst of Skagafjörður fjord in Iceland. The island is the remnant of a 700,000‑year‑old volcano, mostly made of volcanic tuff, forming a massive rock fortress.

It was first mentioned in the Icelandic classic Grettis saga as being the refuge of the outlaw Grettir, who spent his last years there with his brother Illugi and his slave Glaumur. In late autumn of 1031, Grettir was assassinated where he lay virtually dying in his shed on the island. Þorbjörn Öngull and his men were the perpetrators.
