The Meitetsu 3300 series and 3150 series (名鉄3300系・3150系) are commuter electric multiple unit (EMU) train types operated by the private railway operator Meitetsu in Japan since 2004.

[1] The 3300 series trains were based on the earlier 300 series trains, which were the first stainless steel body trains to be operated by Meitetsu, although whereas the 300 series trains had 20 m (65 ft 7 in) long cars with four pairs of sliding doors per side, the 3300 series have 19 m (62 ft 4 in) long cars and three pairs of sliding doors per side.

[1] In January 2015, sets 3303 and 3304 were decorated to mark the 400th anniversary of the death of Tokugawa Ieyasu.

[5] Like the four-car 3300 series trains, the 3150 series trains were based on the earlier 300 series trains, which were the first stainless steel body trains to be operated by Meitetsu, although whereas the 300 series trains had 20 m (65 ft 7 in) long cars with four pairs of sliding doors per side, the 3150 series have 19 m (62 ft 4 in) long cars and three pairs of sliding doors per side.

[1] As of 1 April 2015[update], 16 two-car sets were in operation, formed as shown below, with one driving motored ("Mc") car and one non-powered driving trailer ("Tc") car.
