The TRTA/Tokyo Metro 05 series (営団・東京メトロ05系, Eidan/Tōkyō Metoro 05-kei) is an electric multiple unit (EMU) train type operated on the Tokyo Metro Tozai Line and Tokyo Metro Chiyoda Line Ayase Branch in Japan by the subway operator Tokyo Metro. Some sets have also been shipped to Indonesia, where they operate on the KRL Commuterline system in Jakarta.
A total of 43 ten-car trainsets were built from 1988 to 2004, with a number of variants. Sets 05-125 onward have a redesigned front end, and are called "05N series". Sets 05-114 to 05-118 have wide doors. A further four sets were due to be built, but the plan was changed to use 07 series trains transferred from the Yurakucho Line, so no further 05 series trains were built.
