The EN 300 are a series of EMUs built in 1977 for the Italian railway company SEPSA, used on the commuter railways Circumflegrea and Cumana.

The numbers are EN 301–307 for the railcars and RN 301–307 for the control cars.

The EN 300 were ordered in 1976 to renew the train sets of the SEPSA.

The EN 300 derivate from the ALe 803 of the Ferrovie dello Stato, but with less maximal speed and a shorter loading gauge.
