Chengdong is a district of Xining, the capital of Qinghai Province in northwest China. It is one of four districts that make up the prefecture-level city of Xining.
The name Chengdong means "east of the city," reflecting its position on the eastern side of Xining's urban core. As a district, it forms part of the administrative structure of the provincial capital.
