The Meitetsu 4000 series (名鉄4000系) is a commuter electric multiple unit (EMU) train type operated by Nagoya Railroad (Meitetsu) in Japan since 2008.

The first 4-car set was built in 2008 for use on the Meitetsu Seto Line,[4] entering service on 1 October 2008.

Two sets were delivered during fiscal 2011, bringing the total fleet to 32 vehicles (8 sets) by March 2012.

The 4000 series now consists of 18 four-car sets, thus completely replacing the older types 6000, 6600 and 6750.

Since April 2014, the 4000 series has been the only train type on the Seto Line.
