Zhenzhuquan is a township in the northeastern part of Yanqing District, Beijing, China. It lies in the city's far northern reaches, near the border with Hebei province, in a mountainous area of the Yanqing basin's uplands.
Administratively it is a township rather than a town or subdistrict. It borders Qianjiadian and Baoshan Townships to the north, Liulimiao Town to the east, and Sihai Town to the southeast. As of the 2020 census it had a population of 2,469 residents, making it one of the less densely settled parts of the district.
Its position among several other townships in Yanqing's northeast means it forms part of the rural, sparsely populated belt that surrounds the district's main urban centre. The area is primarily known for its administrative role within Yanqing District rather than as a major destination in its own right.
