Tibet under Yuan rule refers to the Mongol-led Yuan dynasty's rule over Tibet from 1244 to 1354. During the Yuan dynasty rule of Tibet, the region was structurally, militarily and administratively controlled by the Mongol-led Yuan dynasty of China. In the history of Tibet, Mongol rule was established after Sakya Pandita got power in Tibet from the Mongols in 1244, following the 1240 Mongol conquest of Tibet led by the Mongol general with the title doord darkhan. It is also called the Sakya dynasty after the favored Sakya school of Tibetan Buddhism.

Tibet, or Greater Tibet, is a region in the central part of East Asia, covering much of the Tibetan Plateau and spanning about 2,500,000 km2 (970,000 sq mi). It is the homeland of the Tibetan people. Also resident on the plateau are some other ethnic groups such as the Monpa, Tamang, Qiang, Sherpa and Lhoba peoples and, since the 20th century, considerable numbers of Han Chinese and Hui settlers. Since the annexation of Tibet by the People's Republic of China in 1951, the entire plateau has been under the administration of the People's Republic of China. Tibet is divided administratively into the Tibet Autonomous Region, and parts of the Qinghai and Sichuan provinces. Tibet is also constitutionally claimed by the Republic of China as the Tibet Area since 1912. Tibet is the highest region on Earth, with an average elevation of 4,380 m (14,000 ft). Located in the Himalayas, the highest elevation in Tibet is Mount Everest, Earth's highest mountain, rising 8,848.86 m (29,032 ft) above sea level.
