The Mogao Caves, also known as the Thousand Buddha Grottoes or Caves of the Thousand Buddhas, form a system of 500 temples 25 km (16 mi) southeast of the center of Dunhuang, an oasis located at a religious and cultural crossroads on the Silk Road, in Gansu province, China. The caves may also be known as the Dunhuang Caves; however, this term is also used as a collective term to include other Buddhist cave sites in and around the Dunhuang area, such as the Western Thousand Buddha Caves, Eastern Thousand Buddha Caves, Yulin Caves, and Five Temple Caves. The caves contain some of the finest examples of Buddhist art spanning a period of 2,000 years.

Buddhist art is visual art produced in the context of Buddhism. It includes depictions of Gautama Buddha and other Buddhas and bodhisattvas, notable Buddhist figures both historical and mythical, narrative scenes from their lives, mandalas, and physical objects associated with Buddhist practice, such as vajras, bells, stupas and Buddhist temple architecture. Buddhist art originated in the north of the Indian subcontinent, in modern India, Pakistan and Afghanistan, with the earliest survivals dating from a few centuries after the historical life of Siddhartha Gautama from the 6th to 5th century BCE.
