The Hidaka Main Line (日高本線, Hidaka-honsen) is a railway line in Hokkaido, Japan, operated by Hokkaido Railway Company (JR Hokkaido), between Tomakomai Station in Tomakomai and Samani Station in Samani, running along the coast of Hidaka Subprefecture. Services on the 116.0 km (72.1 mi) section of the line beyond Mukawa Station were suspended indefinitely since January 2015 due to storm damage. This section was closed on 1 April 2021 and replaced by a bus service. The closure of this section made the line the second shortest in Japan to be classified as a 'main line', at just 30.5 km (19.0 mi), after the Rumoi Main Line's length of 14.4 km (8.9 mi).
