葛逻禄，乃中亚古代游牧民族，13世纪时称「哈剌鲁」，有“雪”、“雪山”或雪人的意思。该族分为三姓，分别是「谋落部」（或作谋剌）、「炽俟部」（或作婆匐）与「踏实力部」。之后与西迁的回纥15部组成。文献中常称为三姓葛逻禄，曾经与回纥攻灭西突厥，他们与回纥关系密切。

葛逻禄最早游牧于今额尔齐斯河上游与阿尔泰山西南，臣服于西突厥。唐灭西突厥后，分葛逻禄三部置阴山州都督府、大漠州都督府、玄池州都督府，后析大漠州都督府置金附州都督府，隶属于昆陵都护府及后来的北庭大都护府。该族曾协助苏定方灭西突厥，但怛罗斯之战中背叛，造成唐军惨败。后来几乎领有全部西突厥的旧疆。回纥建国后，成为回纥汗国的客部，分左右二厢，左厢从回纥，右厢自立叶护，半独立。

The Karluks (also Qarluqs, Qarluks, Karluqs, Old Turkic: , Qarluq, Persian: خَلُّخ (Khallokh), Arabic قارلوق "Qarluq") were a prominent nomadic Turkic tribal confederacy residing in the regions of Kara-Irtysh (Black Irtysh) and the Tarbagatai Mountains west of the Altay Mountains in Central Asia. They were also known as the Gelolu (simplified Chinese:葛逻禄; traditional Chinese:葛逻禄; pinyin:Géluólù, customary phonetic: Gelu, Khololo, Khorlo or Harluut). They were closely related to the ******. Karluks gave their name to the distinct Karluk group of the Turkic languages, which also includes the ******, Uzbek, and Ili Turki languages.
