The was an electric multiple unit (EMU) train type operated by the Tokyo subway operator Tokyo Metro in Tokyo, Japan. A total of 42 eight-car trainsets were built, between 1988 and 1994, entering service on 1 July 1988 and the final sets were withdrawn by 8 February 2020.[2]
The 03 series trains operated on the Tokyo Metro Hibiya Line, with through-running to and from the Tobu Skytree Line and before 2013, on the Tokyu Toyoko Line.
, the fleet consisted of 40 eight-car sets, formed as shown below, with car 1 at the Naka-Meguro (south) end.[3] Sets consisted of four motored ("M") cars and four non-powered trailer ("T") cars.[3]

The 03 series trains began to be replaced by new 13000 series trains from 25 March 2017.[4] The first set to be withdrawn, set 14, was removed for scrapping in February 2017.[5]
The 03 series was fully retired from the Hibiya Line on 28 February 2020 with no fanfare; Tokyo Metro cited the inconvenience created from the crowding of train enthusiasts during the farewell event for the 6000 series as the main reason for this decision.[6]
Three former 03 series EMUs were resold for use by the Kumamoto Electric Railway in Kumamoto Prefecture between 2018 and 2020.[7] They entered service on 4 April 2019.
On 31 January 2020, Nagano Electric Railway announced the second-hand purchase of a few 03 series units, which would be redesignated as the 3000 series. They're intended to replace the older 3500 series (ex-TRTA 3000 series, themselves too ex-Hibiya Line stock) which currently form the backbone of local service rolling stock on the railway.[8]
Hokuriku Railway plans to buy a total of five 03 series sets for use on the Asanogawa Line. The first two sets arrived at the railway's depot on 11 January 2020.
