纳姆塔尔(Namtar)或纳姆塔鲁(Namtaru)、纳姆塔拉(Namtara)(命运或宿命之意)，是美索不达米亚神话中的一位地狱僚神、冥神，是安、埃列什基伽勒和内尔伽勒(Nergal)的臣僚和神使。

纳姆塔尔是恩利勒与埃列什基伽勒的儿子，生于他父亲强占宁利勒女神之前。 据认为纳姆塔尔主要执掌疾病和虫害。有人说，他掌管着60种能渗入人体不同部位的魔咒疾病；为防止得上这些病疫，人们要向他献祭。据信，亚述人和巴比伦人在征服苏美尔后，继承了他们的这一信念。并将他视作非常重要的命运之神，使他也拥有了一些神的权力。在其他著作中，他们被视为死亡的化身，就像现代理念中的死神一样。

Namtar (or Namtaru, or Namtara; meaning destiny or fate), was a hellish minor deity in Mesopotamian mythology, god of death, and minister and messenger of An, Ereshkigal, and Nergal.

Namtar was the son of Enlil and Ereshkigal; he was born before his father raped the goddess Ninlil. Namtar was considered responsible for diseases and pests. It was said that he commanded sixty diseases in the form of demons that could penetrate different parts of the human body; offerings to him were made to prevent those illnesses. It is thought that the Assyrians and Babylonians took this belief from the Sumerians after conquering them. To some they were the spirit of fate, and therefore of great importance. Apparently they executed the instructions given him concerning the fate of men, and could also have power over certain of the gods. In other writings they were regarded as the personification of death, much like the modern concept of the Grim Reaper.
