The Husan Line is a non-electrified standard-gauge freight-only secondary line of the Korean State Railway located entirely within Namp'o Special City, South P'yŏngan Province, North Korea, running from Husan on the Ryonggang Line to Yangmak.

[1] The Husan Line runs 3.7 km (2.3 mi) along the west side of the Ryongho Reservoir to serve a number of industries around Yangmak.

The line was originally opened by the Chosen Government Railway prior to 1937.

Most freight on the line is outbound from the granite quarry past Yangmak.

A yellow background in the "Distance" box indicates that section of the line is not electrified.
