The Odakyu 8000 series (小田急8000形, Odakyū 8000-gata) is a commuter electric multiple unit (EMU) train type operated by the private railway operator Odakyu Electric Railway in Japan since 1983.

Some cars have a jump seat that folds up to provide space for commuters using wheelchairs.

Built from 1982, the 8000 series was designed to help the Odakyu Electric Railway deal with the increasing number of passengers they had to carry from suburbs into the Tokyo region.

[6] The 8000 series was the last Odakyu trainset to use their distinctive ivory body with blue accents; all future Odakyu commuter trains would use unpainted stainless steel bodies with the same blue accents.

[8][9] It was later announced on 10 May 2024 that one 8000 series set would be transferred to Seibu Railway and enter service on the Kokubunji Line later in 2024 as part of its fiscal 2024 capital investment plan.
