The 153 series (153系, 153-kei^?) was an electric multiple unit (EMU) train type operated by Japanese National Railways (JNR) from 1958 until 1983.

The first trains, initially classified 91 series (91系^?), entered revenue service on 1 November 1958 on Hiei semi express services operating on the Tokaido Main Line between Tokyo and Nagoya. They were renumbered into the JNR three-digit classification system from 1 June 1959.

From 1972, 153 series sets were introduced on Special Rapid services in the Kyoto-Osaka-Kobe area to compete against private railway operators. These were replaced by 117 series EMUs by the end of 1980.
