Nyŏngbyŏn County is a county in North Pyŏngan Province, North Korea. It borders the cities of Kaechŏn and Anju, and covers an area of 504 km2.
The city was heavily fortified during the 15th century as a result of its strategic position, and during the Josŏn dynasty, became a retreat for the aristocratic ryangban due to its fantastic scenery. The city's Yaksan, meaning medicine mountain, was well known for its azaleas; the modern poet Kim So-wol wrote one of his best-known poems on this subject. Two other mountains, Yaksan-dongdae, east of Yaksan, and Moran Hill are also scenic spots. Nyŏngbyŏn also houses many important relics, including the Chŏnju and Sound Buddhist temples, dating from 1345 and 1684 respectively; the Ryuksung Pavilion, famous for "six scenic views" of Nyŏngbyŏn; and the Ch'ŏl'ong Castle, built to protect the city during the Ri dynasty. The south gate of Nyŏngbyŏn, called Mannomun, is also nearby.
Nyŏngbyŏn county is divided into 1 ŭp (town), 1 rodongjagu (workers' district) and 26 ri (villages):
