The Toei 6000 series (東京都交通局6000形^?) is an electric multiple unit (EMU) train type operated by the Tokyo subway operator Tokyo Metropolitan Bureau of Transportation (Toei) on the Toei Mita Line in Tokyo, Japan, between 1968 and 1999, and subsequently on the Chichibu Railway (since 1999), Kumamoto Electric Railway, and KA Commuter Jabodetabek in Indonesia (from 2000 until 2016).

The 6000 series operated on the Toei Mita Line from its opening in 1968.

Originally delivered with unpainted stainless steel front ends, the blue bodyside bands were extended to the front ends from 1988.

Following withdrawal from the Toei Mita Line in 1999 and replacement by Toei 6300 series EMUs, a number of former 6000 series units were resold to other railway operators in Japan and also donated to KA Commuter Jabodetabek in Indonesia.

12 former 6000 series cars were sold to the Chichibu Railway in 1999, where they were reformed as four three-car 5000 series sets.

The original Toei car numbers and subsequent identities were as follows.

72 former 6000 series cars were donated to KRL Jabodetabek (later KA Commuter Jabodetabek) in Indonesia in 2000 as part of an Official development assistance (ODA) programme to upgrade commuter train services in the Jakarta area.

Nine eight-car sets (6121, 6151, 6161, 6171, 6181, 6197, 6201, 6271, and 6281) were shipped to Indonesia, entering revenue service there from August 2000. In 2004, the trainsets were reformed into eight six-car sets and three eight-car sets, made possible by rebuilding some former intermediate cars with new driving cabs. The fleet subsequently underwent further extensive reorganization and rebuilding of driving cars damaged in accidents.
