The KiHa 141 (キハ141系) is a diesel multiple unit (DMU) train type operated by Hokkaido Railway Company on the Sassho Line in Japan since 1990. The cars were rebuilt from former 50 series locomotive-hauled coaches.

The Sasshō Line is a railway line in Japan operated by Hokkaido Railway Company, which connects Sōen in Sapporo and Hokkaidō-Iryōdaigaku in Tōbetu, Ishikari District. Its name is made up of two characters from Sapporo (札幌) and Ishikari-Numata (石狩沼田), the latter of which was the terminus of the line until it was relocated to Shin-Totsukawa in 1972.
