The Xichengyi culture (Ch:西城驿文化) was an ancient culture in the central Heihe River region of the Hexi Corridor, from 2,000 to 1,600 BCE.

[2] It is contemporary with the Qijia culture to its southeast.

[1] Some of its important archaeological sites are Xichengyi, Ganggangwa (where there are also some earlier Machang culture remains), and Huoshiliang (exclusively Xichengyi culture).

[2] The Xichengyi culture practiced bronze smelting extensively, as seen by the quantity of slabs and furnace material (adobe constructions with blast pipes).

[3] The copper ore was from the neighbouring Beishan Mountain.
