Dongkeng is a town in Guangdong province, China, under the jurisdiction of Dongguan, a prefecture-level city. It lies in the Pearl River Delta region, east of Dongguan's urban core.
The town forms part of Dongguan's administrative structure, one of the municipalities that make up the densely developed delta area between Guangzhou and Shenzhen. Its position east of the city centre places it within the broader urban and industrial belt of the delta.
Beyond its administrative status and location, few details are recorded in the available source material. Dongkeng should not be confused with places of the same name elsewhere in China, including in Fujian province.
