The Qilian Mountains (simplified Chinese: 祁连山; traditional Chinese: 祁連山; pinyin: Qílián Shān; Wade–Giles: Ch'i2-lien2 Shan1, also romanized as Tsilien; Mongghul: Chileb), together with the Altyn-Tagh (Altun Shan) also known as Nan Shan (Chinese: 南山, literally "Southern Mountains"), as it is to the south of Hexi Corridor, is a northern outlier of the Kunlun Mountains, forming the border between Qinghai and the Gansu provinces of northern China.
The eponymous Qilian Shan peak, situated some 60 km south of Jiuquan, at , rises to 5,547 m. It is the highest peak of the main range, but there are two higher peaks further south, Kangze'gyai at with 5,808 m and Qaidam Shan peak at with 5,759 m. Other major peaks include Gangshiqia Peak in the east.
The Nan-Shan range continues to the west as Yema Shan (5,250 m) and Altun Shan (Altyn Tagh) (5,798 m). To the east, it passes north of Qinghai Lake, terminating as Daban Shan and Xinglong Shan near Lanzhou, with Maoma Shan peak (4,070 m) an eastern outlier. Sections of the Ming Dynasty's Great Wall pass along its northern slopes, and south of northern outlier Longshou Shan (3,616 m).
The Qilian mountains are the source of numerous, mostly small, rivers and creeks that flow northeast, enabling irrigated agriculture in the Hexi Corridor (Gansu Corridor) communities, and eventually disappearing in the Alashan Desert. The best known of these streams is the Ejin (Heihe) River. The region has many glaciers, the largest of which is the Touming Mengke. These glaciers have undergone acceleration in their melting in recent decades.
The Shiji mentions the "Qilian mountains" together with Dunhuang in relation to the homeland of the Yuezhi. This Qilian however has been suggested to be the mountains now known as Tian Shan, 1,500 km to the west. Dunhuang has also been argued to be the Dunhong mountain. Qilian (祁连) is said to be a Xiongnu word meaning "sky" (Chinese: 天) according to Yan Shigu, a Tang Dynasty commentator on the Hanshu. Sanping Chen (1998) suggested that 天 tiān, 昊天 hàotiān, 祁連 qílián, and 赫連 Hèlián were all cognates and descended from multisyllabic Proto-Sinitic *gh?klien. Schessler (2014) objects to Yan Shigu's statement that 祁連 was a Xiongnu word; he reconstructs 祁連's pronunciation in around 121 BCE as *gɨ-lian, apparently the same etymon as 乾 (☰) the Trigram for "Heaven", in standard Chinese qián < Middle Chinese QYS *gjän < Eastern Han Chinese gɨan < Old Chinese *gran, which Schuessler etymologizes as from Proto-Sino-Tibetan and related to Proto-Tibeto-Burman *m-ka-n, cognate with Written Tibetan མཁའ (Wylie transliteration: mkha') “heaven”.
The Tuyuhun were based around the Qilian mountains.
The mountain range gives its name to Qinghai's Qilian County.
