The E127 series (E127系?) is a DC electric multiple unit (EMU) train type operated on local services by East Japan Railway Company (JR East) in Japan since 1995, and also by the third-sector railway operator Echigo Tokimeki Railway since March 2015 as the ET127 series. The design is derived from the 209 series commuter EMU.
- E127-0 series: 13 x 2-car sets built for the Niigata area (Echigo Line, Hakushin Line, Uetsu Main Line)
- E127-100 series: 12 x 2-car sets for Matsumoto area (Ōito Line, Shinonoi Line)
- ET127 series: 10 x former E127-0 series 2-car sets operated by Echigo Tokimeki Railway (ETR) since March 2015
Thirteen 2-car sets were built by Kawasaki Heavy Industries and Tokyu Car, and delivered to Niigata Depot in March 1995 (sets V1 to V6) and November 1996 (sets V7 to V13) for use on Echigo Line, Hakushin Line, and Uetsu Main Line local services. They entered service on 8 May 1995.
From 14 March 2015, ten former E127-0 series sets were transferred to the ownership of the third-sector railway operating company Echigo Tokimeki Railway for use on the newly named Myōkō Haneuma Line, and reclassified as ET127 series. Set V3 was withdrawn in October 2014, leaving just two sets, V12 and V13, in the ownership of JR East.
Sets are formed as shown below, with one motored "Mc" car and one non-powered trailer "Tc" car.

Twelve 2-car sets were built by Kawasaki Heavy Industries, JR East (Tsuchizaki Factory), and Tokyu Car, and delivered to Matsumoto Depot in November and December 1998 for use on Ōito Line and Shinonoi Line local services. They entered service on 8 December 1998. The external styling differs from the earlier E127-0 series, resembling the 701 series design. Sets A7 to A12 have a second de-icing pantograph on the KuHa trailer car.
