诺伦三女神或诺恩三女神（或省掉「三女神」三字。古诺尔斯语：Norn；英语：The Norns或是复数形nornir），是北欧神话中的命运女神。

诺伦三女神是智能巨人密米尔的三个女儿，另一说是巨人诺尔维（时间）的女儿。

其中大女儿兀儿德（Urd）司掌「过去」，二女儿薇儿丹蒂（Verdandi）司掌「现在」，小女儿斯库尔德（Skuld）司掌「未来」。这三姊妹不仅掌握了人类的命运，甚至也能预告诸神、巨人以及侏儒的命运，她们的出现被视为诸神黄金时代的结束。她们同时也是司掌法律的女神。

在《新埃达》中，兀儿德被称作「高贵之人」，薇儿丹蒂被称作「同样高贵的人」，斯库尔德被称为「第三高贵的人」，同时也称她们作「支配命运的姊妹」（weird sisters），weird是日耳曼语中「命运（wyrd）」的字源。另外她们也被称作「记述的女神」（dieschreiberinnen）用木片雕刻如尼文本。她们的主要任务织造命运之网、以及从兀儿德之泉中汲水浇灌世界之树。

The Norns (Old Norse: norn, plural: nornir) in Norse mythology are female beings who rule the destiny of gods and men. They roughly correspond to other controllers of humans' destiny, the Fates, elsewhere in European mythology.

According to Snorri Sturluson's interpretation of the Völuspá, the three most important norns, Urðr (Wyrd), Verðandi and Skuld, come out from a hall standing at the Well of Urðr (well of fate). They draw water from the well and take sand that lies around it, which they pour over Yggdrasill so that its branches will not rot. These three norns are described as powerful maiden giantesses (Jotuns) whose arrival from Jötunheimr ended the golden age of the gods. They may be the same as the maidens of Mögþrasir who are described in Vafþrúðnismál (see below).
