The Qijia culture (2400 BC - 1900 BC) was an early Bronze Age culture distributed around the upper Yellow River region of Gansu (centered in Lanzhou) and eastern Qinghai, China, it is regarded as one of the earliest bronze cultures. Johan Gunnar Andersson discovered the initial site at Qijiaping (齊家坪) in 1923. Qijia culture was a sedentary culture, based on agriculture, and breeding pigs, which were also used in sacrifices. Qijia culture is distinguished by a presence of numerous domesticated horses, and practice of oracle divination, the metal knives and axes recovered apparently point to some interactions with Siberian and Central Asian cultures, in particular with the Seima-Turbino complex. Archeological evidence points to plausible early contact between the Qijia culture and Central Asia. During the late stages of the culture, the Qijia culture retreated from the west and suffered a reduction in population size. Qijia culture produced some of the earliest bronze and copper mirrors found in China. Extensive domestication of horses are found at many Qijia sites.
The archaeological sites at Lajia, Huangniangniangtai, Qinweijia, and Dahezhuang  are associated with the Qijia culture.
