The KiHa 100 series (キハ100系^?) is a series of diesel multiple unit (DMU) trains operated since 1990 by East Japan Railway Company (JR East) on non-electrified rural lines in Japan.

A total of 247 vehicles were built between 1989 and 1999 by Fuji Heavy Industries and Niigata Transys.

KiHa 100 and 110 series DMUs are based at the following depots and used on the following lines.

The first four pre-production cars were delivered from Niigata Tekkō (now Niigata Transys) to Ichinoseki Depot in January and February 1990. Cars KiHa 100-1 and -3 were equipped with one Cummins DMF14HZ 330 hp engine per car, while cars KiHa 100-2 and -4 were each equipped with one Komatsu DMF11HZ 330 hp engine. The four pre-production cars were initially delivered with black front ends, but these were subsequently repainted white and green to match the later production series cars.

Four production-series cars were then delivered from Fuji Heavy Industries in March 1991. These were each equipped with one Komatsu DMF11HZ 330 hp engine. Differences from the four pre-production series cars included abandoning of the three pairs of tip-up seats near the doorways, and elimination of the dummy exterior window at the toilet position.

38 2nd-batch cars were delivered from June to October 1991. Cars 9 to 29, built by Fuji Heavy Industries, were delivered to Morioka Depot, and cars 30 to 46, built by Niigata Tekkō, were delivered to Ichinoseki Depot. Cars 9 to 29 are each equipped with one Niigata Tekkō DMF13HZ 330 hp engine, and cars 30 to 46 are each equipped with one Komatsu DMF11HZ 330 hp engine. Differences from the earlier 1st-batch cars included solid front-end skirts instead of the earlier pipe-style skirts.

Five KiHa 100-200 cars were delivered from Fuji Heavy Industries to Hachinohe Depot in 1993. The cab sections were extended by 250 mm to provide additional crash protection, giving an overall car length of 17,000 mm. Cars are each equipped with one Komatsu DMF11HZ 330 hp engine. A wheelchair space was provided next to one doorway, giving a seating capacity of 44 and total capacity of 103 passengers (59 standing).
