The Odakyu 2000 series (小田急2000形, Odakyū 2000-gata) is a commuter electric multiple unit (EMU) train operated by the private railway operator Odakyu Electric Railway in the Tokyo area of Japan since March 1995.

The design was based on the earlier 1000 series sets, with some of the passenger doors widened from 1,300 to 1,600 mm (51 to 63 in) to help reduce station dwell times.

In 2009, set 2052 received full-colour LED destination displays.

[6] Set 2051 received an altered blue waistline stripe in 2012.

[7] As of October 2024,[update] the revised colour scheme has been applied to the entire 2000 series fleet except for set 2059.
