The Pukbunaeryuk Line, also called the Hyesan–Manp'o Ch'ŏngnyŏn Line after the only completed stage of three planned stages, is an electrified standard-gauge secondary trunk line of the Korean State Railway in Chagang and Ryanggang Provinces, North Korea, connecting the Manp'o Line at Manp'o to the Paektusan Ch'ŏngnyŏn Line at Hyesan. It also connects to the China Railway Meiji Railway via the Ji'an Yalu River Border Railway Bridge between Manp'o and Meihekou, China.

The Pukbunaeryuk Line was to have been a northern east–west trunk line of 450 km (280 mi) on the Manp'o–Hyesan–Musan–Hoeryŏng route, but this plan has not been realised.

There are 42 stations on the line, of which Chasŏng, Hwap'yŏng, P'op'yŏng Ch'ŏngnyŏn, and Mint'ang are dedicated freight consolidation points; the stations of Chŏnp'yŏng, Tuji, Sinp'a Ch'ŏngnyŏn, Ryanggang Sinsang, and Insan are served only by passenger trains. The line has 76 tunnels totalling over 26 km (16 mi) in length, and 116 bridges with a total length of over 6.3 km (3.9 mi) - bridges make up 3.3% of the total length of the line, whilst tunnels account for 12.8% of the total route length.

There are locomotive facilities at Manp'o and Hyesan, and formerly at P'op'yŏng; Hyesan also has shops for maintenance of passenger and freight cars.
