Haixi Mongol and Tibetan Autonomous Prefecture, locally also known as Qaidam Prefecture (mong. Qaidam; tib. Caindam; chin. Chaidamu), is an autonomous prefecture occupying much of the northern tier of as well as part of the southwest Qinghai province, China. It has an area of 325,785 square kilometres (125,786 sq mi) and its seat is Delingha. The name of the prefecture literally means "west of (Qinghai) Lake."

Geladandong Mountain, the source of the Yangtze River, is located here.

After 1949, the People's Government of Dulan County was founded and the area was renamed Dulan Autonomous District (都兰自治区); in 1954, Dulan was renamed Haixi Mongol, Tibetan and Kazakh Autonomous District (海西蒙藏哈萨克族自治区) and in 1955, Haixi Mongol, Tibetan and Kazakh Autonomous Prefecture (海西蒙藏哈萨克族自治州). In 1963, it was renamed "海西蒙古族藏族哈萨克族自治州" (English the same, "蒙藏哈萨克族"->"蒙古族藏族哈萨克族"). In 1985, after the Kazakhs had returned to Xinjiang, it was again renamed Haixi Mongol and Tibetan Autonomous Prefecture.

As of the 2010 census, Haixi had 489,338 inhabitants, giving it a population density of 1.5 inhabitants per km².
