The Chōsen Railway Company (Japanese: 朝鮮鉄道株式会社, Chōsen Tetsudō Kabushiki-gaisha; Korean: 조선철도주식회사, Joseon Cheoldo Jusikhoesa), was a privately owned railway company in Japanese-occupied Korea.

In addition to extensively investing in busses and in the development of Hwanghae Province, in 1927, Chōtetsu established a subsidiary company, the North Chōsen Colonial Railway, to build and operate a line in the northeastern part of Korea.
