The Odakyu 60000 series MSE (小田急60000形, Odakyū 60000-gata) (Multi Super Express) is a Romancecar electric multiple unit (EMU) train type operated by the private railway operator Odakyu Electric Railway in Japan since March 2008.

The trains are used on Odakyu through service to the Tokyo Metro Chiyoda Line, and some trains also travel over the Tokyo Metro Yurakucho Line, making it the first limited express train with reserved seats to operate through a subway line in Tokyo.

As of 1 April 2022[update], the fleet consists of five 6-car sets and three 4-car sets (42 vehicles in total), formed as follows, with car 1 at the Odawara end and car 10 at the Shinjuku (Tokyo) end.

In 2009, the 60000 series MSE was awarded the Blue Ribbon Award, presented annually in Japan by the Japan Railfan Club for railway vehicles voted as being the most outstanding design of the year.
