The Sinheung Railway (Japanese: 新興鉄道株式会社, Shinkō Tetsudo Kabushiki Kaisha; Korean: 신흥철도주식회사, Sinheung Cheoldo Jusikhoesa), was a privately owned railway company in colonial era Korea.

It was a subsidiary of the Chōsen Railway (Chōtetsu), colonial Korea's largest privately owned railway company, established in 1930 to operate a number of lines opened by Chōtetsu and one of its predecessors, the Chōsen Forestry Railway.

[1] The Sinheung Railway was bought and absorbed by Chōtetsu on 22 April 1938;[9] Chōtetsu subsequently split the Sinheung Railway's network into four separate lines: the Hamnam Line (Hamheung–Hamnam Sinhung/Sangtong/Jangpung), the Songheung Line (Hamnam Sinheung–Bujeonhoban), the Jangjin Line (Sangtong–Sasu), and the Namheung Line (West Hamheung–Seohojin).
