The Tokyo Metro 2000 series (東京メトロ2000系, Tōkyō Metoro 2000-kei) is an electric multiple unit (EMU) train type operated by Tokyo Metro for use on the Marunouchi Line in Tokyo, Japan. They serve as a replacement for the Tokyo Metro 02 series that was in service on the Marunouchi Line from 1988 to 2024.^[3]

The trains are built by Nippon Sharyo and Kinki Sharyo, with Toshiba supplying the electrical equipment.^[4] They are fitted with permanent magnet synchronous motors and silicon carbide traction inverters, which are expected to reduce the power consumption by about 20%, compared to the Tokyo Metro 02 series currently in service on the Marunouchi Line.^[5][6]

Self-steering axles similar to those of the 1000 series are fitted to the bogies.^[4]

The trains are formed as six-car sets.^[4]

The seating accommodation consists of longitudinal seating.^[4] The cars are air conditioned, with feature round windows at the car ends. They also have power outlets for passengers to charge their mobile devices.^[7]
