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

A total of 44 cars were built, between 1990 and 1995, divided into four main types: KiHa 141, KiHa 142, KiHa 143, and KiSaHa 144.

14 KiHa 141 cars were built between 1990 and 1993 from surplus 50 series OHaFu 51 locomotive-hauled coaches, using the bogies and gearboxes from withdrawn KiHa 22 and KiHa 56 DMUs. These cars are formed as two-car sets with KiHa 142 cars. The KiHa 141 cars are powered by one DMF13HS 250 hp engine, and retain the original toilet of the 50 series coaches. These cars are not air-conditioned.

The build dates and former identities are as shown below.

15 KiHa 142 cars were built between 1990 and 1995 from surplus 50 series OHaFu 51 locomotive-hauled coaches, using the bogies and gearboxes from withdrawn KiHa 22 and KiHa 56 DMUs. These cars are formed as two-car sets with KiHa 141 cars. The KiHa 142 cars are powered by two DMF13HS 250 hp engines, and the original toilet of the 50 series coaches was removed during rebuilding. These cars are not air-conditioned.

KiHa 142-14 was fitted with modified passenger door control circuits in 1995 and renumbered KiHa 142-114. KiHa 142-201 was built in 1995 from former 50 series coach OHaFu 51-30 for use in conjunction with KiHa 143 cars.

The build dates and former identities are as shown below.

11 KiHa 143 cars were built in 1994 from surplus 50 series OHaFu 51 locomotive-hauled coaches to provide additional capacity on the Sassho Line. These cars are formed as two-car sets, consisting of KiHa 143-100 cars at the Sapporo end and KiHa 143-150 cars at the opposite end. The KiHa 143 cars are powered by two DMF13HZD 450 hp engines, and used bogies based on the KiHa 150 design. The KiHa 143-150 cars retain the original toilet of the 50 series coaches. All cars were fitted with air-conditioning from 1996.

Passenger accommodation consists of transverse seating bays arranged 2+1 abreast, with longitudinal bench seating at the car ends.
