Xindian culture (Chinese 辛店 文化, Xindian Wenhua) was a Bronze Age culture in the Gansu and Qinghai provinces of China. Xindian culture is dated ca. 1500–1000 BCE, a radiocarbon testing of an artefact produced a date around 1000 BCE, which roughly corresponds to the (Western) Zhou period of the Central Plain (Zhongyuan) area (in the middle and lower course of the Yellow River). Xindian culture is named after a site discovered in 1923-24 in Xindian Lintao. The culture was mainly located in Gansu in the middle and lower course of the Tao He 洮河 and Daxia He 大 夏河 rivers, and in Qinghai in the basin of the Huang Shui 湟 水 river. Xindian culture was predominantly agricultural, with breeding pigs and cattle, at the sites of the culture were found bronze castings and traces of copper smelting production. Xindian culture belongs to the painted pottery cultures found in Central Asia, India, and China, among others.
Xindian culture is connected with the late Qijia culture, the pottery evidence demonstrates a cultural continuity, though genetically it is not related with it. In the same area in close proximity are distributed early sites of the contemporary neighboring Siwa culture, though Xindian culture and Siwa culture followed their own paths of development. The later Xindian culture expanded westard and came closer to the Kayue culture, it was possibly absorbed by the Kayue culture.
