The Tobu 9000 series (東武9000系, Tōbu 9000-kei?) is a commuter electric multiple unit (EMU) train type operated by Tobu Railway in Japan.
First entering service in 1981 on the Tōbu Tōjō Line, this was the first stainless steel EMU type to be introduced by Tobu. A total of ten 10-car sets were ultimately built for use on through-running services over the Tokyo Metro Yūrakuchō Line and Tokyo Metro Fukutoshin Line, as well as Tōjō Line services between Ikebukuro and Ogawamachi.
