The 101 series (101系, 101-kei) was a DC electric multiple unit (EMU) commuter train type introduced in 1957 by Japanese National Railways (JNR), and formerly operated by East Japan Railway Company (JR East) and West Japan Railway Company (JR-West). The last remaining trains were withdrawn in November 2003.
The prototype 101 series set was delivered in June 1957, as a 10-car (4+6-car) set classified as 90 series with all cars motored. Cab cars were numbered MoHa 90500 to 90503, and the intermediate cars were numbered MoHa 90000 to 90005. Production sets were delivered from March 1958, differing visually from the prototype in having exposed rain gutters along the top of each car. The 90 series was reclassified as 101 series from 1959, with the prototype set cars numbered in the 900 subseries. The prototype set was modified in 1962 to bring it up to production set standards.

101 series trains operated on the following lines.
A number of former 101 series trains were sold to the private railway operator Chichibu Railway in Saitama Prefecture in 1986, where they operated as 3-car 1000 series sets until March 2014.
