Hotan, sometimes spelled "Khotan" in older sources, is the seat of the Hotan Prefecture in Xinjiang, China. It was previously known in Chinese as 于窴/於窴 (pinyin: Yú tián) and to 19th-century European explorers as Ilchi.

With a population of 114,000 (2006), Hotan is an oasis town lying in the Tarim Basin, just north of the Kunlun Mountains, which are crossed by the Sanju Pass, and the Hindu-tagh, and Ilchi passes. The town, located southeast of Yarkand and populated almost exclusively by Uyghurs, is a minor agricultural center. An important station on the southern branch of the historic Silk Road, Hotan has always depended on two strong rivers - the Karakash River and the Yurungkash River, the Black and White Jade rivers respectively - to provide the water needed to survive on the southwestern edge of the vast Taklamakan Desert. The Yurungkash still provides water and irrigation for the town and oasis.
