Kangxiwar (Chinese: 康西瓦; pinyin: Kāng xī wǎ; Uyghur: كەڭشىۋەر)[a] is the location of a deserted town on the southwest side of the Kunlun Mountains.

It is on the bank of the Karakash River in the western Xinjiang Uyghur Autonomous Region of the People's Republic of China.

A fort was set up by the princely state of Jammu and Kashmir (part of the British Indian Empire) downstream near Xaidulla to help protect the caravans.

[18][19] During the 1962 Sino-Indian War, the PLA's Xinjiang Military Command set up the forward headquarters for its operations in the western sector (Aksai Chin) at Kangxiwar.

The 2nd Infantry Regiment of Xinjiang was stationed here and controlled the bases at Tianwendian, Heweitan, Kongka Pass and in Ngari.
