The Longxing Monastery or Longxing Temple is an ancient Buddhist monastery located in the town of Zhengding in Hebei Province, China, approximately 15 kilometres (9.3 mi) north of the provincial capital of Shijiazhuang. It has been referred to as the "Best Temple south of Beijing".

Zhengding, originally Zhending, is a county in southwestern Hebei Province, North China, located approximately 260 km (160 mi) south of Beijing, capital of China. It is under the administration of the prefecture-level city of Shijiazhuang, the capital of the province, and has a population of 594,000. Zhengding has been an important religious center for more than 1,000 years, from at least the times of the Sui dynasty to the Qing dynasty. It is the founding place of several major schools of Chan Buddhism. However, many former religious building complexes have been severely damaged throughout history. A noted temple is the Longxing Monastery, where the historical building ensemble has been preserved almost intact. Furthermore, four famous pagodas, each with its own architectural style, are still standing.
