The Tokyu 3000 series (東急3000系, Tōkyū 3000-kei) is a Japanese commuter electric multiple unit (EMU) train type operated by Tokyu Corporation in the Tokyo area of Japan. Introduced into service on 16 April 1999 on the Tokyu Toyoko Line as a sole eight-car set, a total of 78 vehicles, which would form 13 six-car sets, were built by Tokyu Car Corporation between 1999 and 2001 for use on Tokyu Meguro Line inter-running services to the Tokyo Metro Namboku Line, Toei Mita Line, and Saitama Rapid Railway Line. Between 2022 and 2023, 26 new cars were built to lengthen all 13 sets into eight-car sets ahead of the opening of Tokyu Shin-Yokohama Line and inter-running with Sotetsu lines via the Shin-Yokohama Line.
