The 8000 Series is a four-door commuter-type electric multiple unit built by Tokyu to become the new standard train for its train lines.

By the late 1960s, the Tokyu Corporation had gained much experience in building and operating stainless steel cars and in 1969, it decided to build the 8000 Series, which was its first four-door 20m car.

The 8000 Series was revolutionary in many ways. It was the first production train in the world to use field-chopper control, which allowed for energy-efficient regenerative braking. It was also the first production train in Japan to adopt a one-handle master controller.

The equipment of the 8000 Series was later also used on the 8500, 8090 and 8590 Series. All of these trains are considered part of the greater 8000 Series.
 
The 8000 Series was operated mainly on the Toyoko Line and the Ōimachi Line. Some cars were used as middle cars for the 8500 Series trains on the Denentoshi/Shin-Tamagawa Line.

8000 Series trains were originally unpainted, but were later given a red stripe on each end car to improve visibility. Some trains were given the black and red Kabuki color paint scheme during the 1990s when they received updates.

8000 Series trains were retired from service with Tokyu in 2008, but some have been sold to the Izukyu Corporation where they operate as the Izukyu 8000 Series. Two formations were exported to Indonesia where they are operated by PT Kereta Api on the KRL Jabotabek mass transit system.
