Haidong (Chinese: 海东市; pinyin: Hǎidōng shì) is a prefecture-level city of Qinghai province in Western China. Its name literally means "east of the (Qinghai) Lake." On 8 February 2013 Haidong was upgraded from a prefecture (海东地区) into a prefecture-level city.^[3] Haidong is the third most populous administrative division in Qinghai after Xining and Golmud.

Haidong was historically populated by the Qiang people, although the area has been inhabited as early as 6000 years ago. In 121 BC the area was captured by Huo Qubing, defeating the Xiongnu. In 399 AD the Xianbei founded the state of Nanliang, with its capital in Ledu District.^[4]
