Hokkaido Colliery and Railway Company (北海道炭礦鉄道, Hokkaidō Tankō Tetsudō)^[1] was a company engaged in coal mining, railway operation and shipping in Hokkaidō, Japan.

The company was established in 1889 when the state-owned Horonai Coal Mine (幌内炭鉱, Horonai Tankō) and Horonai Railway were sold to the company. The company developed coal mines and transported coal to consumers by its own railways and a fleet of steamships.^[2]

The railway of the company was nationalized on October 1, 1906 under the Railway Nationalization Act. At this time the company was renamed Hokkaido Colliery & Steamship Co., Ltd. (北海道炭礦汽船, Hokkaidō Tankō Kisen), which continued mining until 1995 and is in business of coal importing from Russia as of 2014.^[2]

As of September 30, 1906^[3]

The Muroran–Iwamizawa section and the Iwamizawa–Otaru section are part of the Muroran Main Line and the Hakodate Main Line respectively today. The remaining Otaru–Temiya section became the Temiya Line, which was closed in 1985.
