The Aksu River (Uyghur: ئاقسۇ دەرياسى, Ақсу дәряси, ULY: Aqsu deryasi; simplified Chinese: 阿克苏河; traditional Chinese: 阿克蘇河; pinyin: Ākèsù hé; means "white/clear water" in Uyghur and Kyrgyz languages) is a transboundary river in the Xinjiang province in China and Ak-Suu District of Issyk Kul Province of Kyrgyzstan. In Kyrgyzstan it is known as the Saryjaz River (Kyrgyz: Сарыжаз). The total length of the river is 282 kilometres (175 mi), of which 197 kilometres (122 mi) are in Kyrgyzstan. The Aksu River is the only one of the Tarim's source rivers to run throughout the year.
The river takes its roots at the Semënov glacier in the Central Tian Shan mountains of Kyrgyzstan, close to the tripoint with Kazakhstan and China. From here it first runs towards the west, before turning south and breaking through the high mountains and into Xinjiang in the northern parts of the Tarim Basin. At the city of Aksu it meets its main tributary, the Toshkan, which flows in from the west. After the confluence the river continues south and enters the northern edge of the Taklamakan Desert, where it joins the Tarim River.
