Changshaoying is a Manchu Ethnic Township in the northeastern part of Huairou District, Beijing, China. It lies in the city's far northern mountainous fringe, bordering Hushiha Town to the northeast, Maquanzi Village to the east, Majiayu Town to the southeast, Tanghekou Town to the southwest, and Labagoumen Manchu Ethnic Township to the northwest.
The township had a population of 5,378 as of 2020. Its name, Changshaoying, translates literally as "Long Whistle Barrack", a reference to its historical role as a garrison settlement.
As an ethnic township, Changshaoying is one of the administrative units in Beijing designated for the Manchu population, a status shared with neighbouring Labagoumen. It forms part of Huairou District's sparsely populated northern border zone, where the district meets neighbouring Hebei province.
