The Tokyu Corporation (東京急行電鉄株式会社, Tōkyō Kyūkō Dentetsu Kabushiki-gaisha^?) (TYO: 9005), also known in Japanese as Tōkyū Dentetsu (東急電鉄^?) for short, is a major private railway operator in the Greater Tokyo Area of Japan. Its headquarters are in Shibuya, Tokyo.

It was formed on September 2, 1922 as the Meguro-Kamata Electric Railway (目黒蒲田電鉄, Meguro Kamata Dentetsu^?), and was later known as the Tokyo-Yokohama Electric Railway (東京横浜電鉄, Tōkyō Yokohama Dentetsu^?) before gaining its current name in 1943. From 1944 to 1948, it also owned the companies now known as the Keihin Electric Express Railway, Keio Corporation, and Odakyu Electric Railway. During this time, it was colloquially known as Dai-Tokyu (lit. Great Tokyu).

Additionally, Tōkyū operates the ■ Kodomonokuni Line (Nagatsuta Station - Kodomonokuni Station, 3.4 km) under contract with and on behalf of Yokohama Minatomirai Railway Company.

The Tokyu Group also owns two railroad companies (Ueda Kōtsū, Izukyū Corporation), several bus companies, a major upscale department store chain called Tokyu in Japan and overseas (such as in MBK Center in Bangkok, Thailand), and Tokyu Hands stores (except for the two locations in Nagoya, which are owned by Sanko Creative Life, Inc., and operated under license).
