The Tokyu 3000 series (東急3000系, Tōkyū 3000-kei) is a Japanese commuter electric multiple unit (EMU) train type operated by Tokyu Corporation in the Tokyo area of Japan. Introduced into service on 16 April 1999 on the Tokyu Toyoko Line as a sole eight-car set, a total of 78 vehicles, which would form 13 six-car sets, were built by Tokyu Car Corporation between 1999 and 2001 for use on Tokyu Meguro Line inter-running services to the Tokyo Metro Namboku Line, Toei Mita Line, and Saitama Rapid Railway Line.

Between 2022 and 2023, 26 cars were built to augment the fleet into eight-car formations ahead of the introduction of Sotetsu line through services via the Tokyu Shin-Yokohama Line.

The 3000 series sets are used on Tokyu Meguro Line and Tokyo Metro Namboku Line, Toei Mita Line, and Saitama Rapid Railway Line inter-running services.^[2] In March 2023, they began running on the Tokyu Shin-Yokohama Line, the Sotetsu Shin-Yokohama Line, the Sotetsu Main Line, and the Sotetsu Izumino Line.

As of 1 April 2016^[update], the fleet consists of 13 six-car sets based at Motosumiyoshi Depot, formed as follows with three motored (M) cars and three unpowered trailer (T) cars. Car 1 is at the Meguro (northern) end, and car 6 is at the Hiyoshi (southern) end.^[3]

• The "M" and "M1" cars are each fitted with two single arm pantographs.^[3]
• Car 4 is designated as being mildly air-conditioned.^[3]

The first set, 3001, initially ran as an eight-car formation on the Tokyu Toyoko Line, as shown below, with the Tc2 car at the Shibuya (northern) end.^[1]

The two M1 cars each had two single-arm pantographs.^[1]

Seating is longitudinal bench seating throughout.^[2] Wheelchair spaces are provided in cars 2 and 5.^[3]

The first 3000 series set, 3001, entered service in 1999, initially as an eight-car formation used on the Tokyu Toyoko Line.^[2] This was subsequently reformed as a six-car set following delivery of the rest of the fleet destined for the Meguro Line.^[2] A total of 13 six-car sets (78 vehicles) were built by 2001.^[2]

On 26 March 2019, Tokyu Corporation announced that the entire Meguro Line fleet, including the 3000 series fleet, would be lengthened from six cars to eight cars from the first half of fiscal 2022.^[4] Six of the additional cars were completed in late March 2022 and transported to Nagatsuta depot. As of February 2023, all sets have been lengthened to eight cars.^{[5][additional citation(s) needed]} The new cars are based on the design of the 5000 series,^[6] thus featuring several external and internal differences from the original 3000 series cars.^[7]
