The Tokyu 5000 series (東急5000系?, Tōkyū 5000-kei) is an electric multiple unit (EMU) train type operated by the private railway operator Tokyu Corporation since 2002 on many of its commuter lines in the Tokyo area of Japan.

First introduced in 2002, the design is based on the JR East E231 series commuter train, also manufactured by Tokyu Car Corporation (now J-TREC) in Yokohama.

All trains are equipped with interior LCD screens, displaying the station names, and automatic announcements in both Japanese and English. The 5000 series uses blue seat moquette fabric, while the 5050 and 5080 series have red seat moquette.

All sets use the same driver's cab, with a gray color, and a single 'T' shaped brake and throttle controller. There are four throttle steps, and seven brake steps. The speedometers are equipped with ATC. To the right of the speedometer is an information screen, showing the run type (local, express, etc.), and information of the individual cars. This touch screen computer can also control interior temperature and lights.

These are 10-car sets first introduced on the Den-en-toshi Line from May 2002. These sets are distinguished by a green stripe above the doors. 6-door cars were inserted into some of the sets between 2005 and 2007, with sets 5105 onward having three 6-door cars per set (cars 4, 5, and 8). The 5000 series is fitted with CS-ATC and Tobu ATS (TSP) in order to run through the Tokyo Metro Hanzomon Line, and onward over the Tobu Skytree Line to Tōbu-Dōbutsu-Kōen, Tobu Isesaki Line to Kuki, and Tobu Nikko Line to Minami-Kurihashi. These sets are based at Tokyu's Nagatsuta depot, and are powered by Hitachi motors with VVVF inverters.
