The Tokyo Metro 6000 series (東京メトロ6000系, Tōkyō Metoro 6000-kei) was an electric multiple unit (EMU) train type operated by the Tokyo subway operator Tokyo Metro on the Tokyo Metro Chiyoda Line in Tokyo, Japan from 1971 to 2018. A number of trainsets have been exported to Indonesia for use by Kereta Commuter Indonesia following their withdrawal in Japan.

The trains have 20 m aluminium 4-door cars, and are used on the Chiyoda Line, as well as Odakyu Odawara Line, and Joban Line (all-stations "local" services). The sole three-car set was used on the Chiyoda Line Kita-Ayase branch line.
