Xiong'an New Area is a state-level new area in the Baoding area of Hebei, China. Established in April 2017, the area is located about 100 kilometers (62 mi) south of Beijing and 50 kilometers (31 mi) east of downtown Baoding. Its main function is to serve as a development hub for the Beijing-Tianjin-Hebei (Jing-Jin-Ji) economic triangle. Additionally, nonessential functions of the Chinese capital are expected to migrate here, including offices of some state-owned enterprises, government agencies, and research and development facilities. The city is planned to be erected by 2035, and to be completed by the middle of the 21st century, with a planned population of 5 million people.

The area covers the counties of Xiong, Rongcheng and Anxin. Its name is a compound of the first elements of the names of two of them: Xiong and Anxin. The construction of the area is described as part of the "millennium strategy" (千年大计). Unlike other "new areas", Xiong'an's development is taking place under the direct oversight of the Central Committee of the Chinese Communist Party (CCP) and the State Council. The temporary government office of the New Area is located in Ao Wei International Hotel (Ao Wei Mansion) in Rongcheng.

Xiong'an New Area is located in the North China Plain, between 38°43' and 39°10' north latitude and 115°38' to 116°20' east longitude, 105 km from Beijing and Tianjin, 155 km from Shijiazhuang, 30 km from Baoding, 55 km from Beijing Daxing Airport. It is located at the geometric center of major cities in the Beijing–Tianjin–Hebei region. According to Xu Kuangdi, its location was also motivated by the traditional Chinese philosophy of positioning a city near mountains, rivers, and along axial lines.

Xiong'an's layout mixes urban and natural spaces organized in a manner termed "one center, five subcenters, and multiple nodes". As of 2024, 74,000 new trees had been planted in Xiong'an.

Xiong'an is planned as a Smart City. Its urban design is based on the idea of the "fifteen minute lifecycle" in which all the goods and services needed by an urban person should be available within a fifteen minute walk.

Xiong'an is well-endowed in water features and resources, which is comparatively unusual for north China. The area is located in the Daqing River system of the Haihe River Basin. The average river network density is 0.12–0.23 km per 1 km². Baiyang Lake, northern China's largest freshwater lake, is also included within the new area. The project aims to support restoration of the wetlands surrounding the lake.

Baiyang Lake is Xiong'an's most significant natural feature, including for its cultural and historical significance. It is noted for its scenic beauty. Many Chinese people know of the lake from movies and literature which depict its use by local residents and CCP guerrillas during the Second Sino-Japanese War.

The area is dry and rainy in spring, wet and rainy in summer, cool and dry in autumn, and cold and not snowy in winter. According to the meteorological data of Rongcheng County from 1968 to 2016, the annual average temperature is 12.4°C, the record high temperature is 41.2°C, the record low temperature is -22.2°C, the annual sunshine hour is 2298.4 hours. The average precipitation is 495.1 mm.
