Heng Shan or Heng Mountain (simplified Chinese: 恒山; traditional Chinese: 恆山; pinyin: Héng Shān) in Shanxi Province is one of the Five Great Mountains. At 2,017 m, it is one of the five tallest peaks in China Proper. Heng Shan in Shanxi Province is sometimes known as the Northern Heng Shan, and the one in Hunan Province as Southern Heng Shan (Chinese: 衡山; pinyin: Héng Shān). Both mountains have the same pronunciation in Chinese, and the Southern Heng Shan is also one of the Five Sacred Mountains.

Like the other mountains in China with strong Taoist presence, Heng Shan has been considered a sacred mountain since the Zhou Dynasty. Due to its northerly location, the mountain has made it impossible for pilgrimages by the Chinese to take place for much of its history. Because of this, Hengshan is not nearly as religiously important in China as the other Taoist mountains.

During the Han Dynasty, a temple called the Shrine of the Northern Peak (Beiyue Miao), dedicated to the mountain god was built on Hengshan's slopes. While periodically destroyed and rebuilt, this temple has an uninterrupted history from Han times to the present day. During times of occupation by non-Han Chinese people, worship to Hengshan was done at the Beiyue Temple in Quyang.

 Shanxi (help·info) (Chinese: 山西; pinyin: Shānxī; Wade–Giles: Shan-hsi; Postal map spelling: Shansi) is a province of the People's Republic of China, located in the North China region. Its one-character abbreviation is "晋" (pinyin: Jìn), after the state of Jin that existed here during the Spring and Autumn Period.

The name Shanxi literally means "mountain's west", which refers to the province's location west of the Taihang Mountains. Shanxi borders Hebei to the east, Henan to the south, Shaanxi to the west, and Inner Mongolia to the north and is made up mainly of a plateau bounded partly by mountain ranges. The capital of the province is Taiyuan.

Shanxi, the territory of state of Jin during the Spring and Autumn Period (722 BC - 403 BC), underwent a three-way split into the states of Han, Zhao and Wei in 403 BC, the traditional date taken as the start of the Warring States Period (403 BC - 221 BC). By 221 BC all of these states had fallen to the state of Qin, which established the Qin Dynasty (221 BC - 206 BC).
