Gaochang (Chinese: 高昌; pinyin: Gāochāng; Old Uyghur: Qocho), also called Khocho, Karakhoja, Qara-hoja, Kara-Khoja or Karahoja (قاراغوجا in Uyghur), was an ancient oasis city on the northern rim of the inhospitable Taklamakan Desert in present-day Sanbu Township, Xinjiang, China. The site is also known in published reports as Chotscho, Khocho, Qocho or Qočo. During the Yuan dynasty and Ming dynasty, Gaochang was referred to as "Halahezhuo" (哈拉和卓) (Qara-khoja) and Huozhou. Artistic depictions of the city have been published by Albert von Le Coq. Gaochang is considered in some sources to have been a "Chinese colony", that is, it was located in a region otherwise occupied at the time by West Eurasian peoples.
A busy trading center, it was a stopping point for merchant traders traveling on the Silk Road. It was destroyed in wars during the 14th century and old palace ruins and inside and outside cities can still be seen today. Along with other sites along the historic Silk Road, Gaocheng was inscribed in 2014 on the UNESCO World Heritage List as the Silk Roads: the Routes Network of Chang'an-Tianshan Corridor World Heritage Site.
