Yanqing District (Chinese: 延庆区; pinyin: Yánqìng Qū), formerly known as Yanqing County before 2015, is a district of the municipality of Beijing located northwest of the city proper of Beijing, 74km away from the city center. The district consists of 3 subdistricts, 11 towns and 4 townships, and borders the Beijing districts of Huairou to the east and Changping to the south as well as the Hebei counties of Huailai to the west and Chicheng to the north.

Eventually in 1952, it was reassigned to the Zhangjiakou Special Zone [zh] in Hebei Province, and in 1958, it was transferred to Beijing. In November 2015, the State Council of the People's Republic of China approved the adjustment of the administrative divisions of Beijing, and Yanqing County was abolished and established as a district.
