 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).
