The Tokyo Toden (東京都電, Tōkyō Toden^?) or simply Toden, is the streetcar network of Tokyo, Japan. Of all its former routes, only one, the Toden Arakawa Line, remains in service. The Tokyo Metropolitan Bureau of Transportation operates the Toden. The formal legal name is Tokyo-to Densha. Its nickname, "Toden," distinguished it from the "Kokuden" (electrified lines of the Japanese National Railways).

At its peak, the Toden system boasted 41 routes with 213 kilometers of track. However, the increase in reliance on automobile traffic resulted in reductions in ridership, and from 1967 to 1972, 181 km of track were abandoned as the Bureau changed its emphasis to bus and subway modes of transportation.

This is the list of former lines, listed according to their official names. Correspnding routes are those of 1962. The first section of the lines opened in the listed opening years, while the last section of the lines closed in the listed closing years.

They were the only lines with a gauge of 1067 mm. The rest of the network had a gauge of 1372 mm.

Tokyo (東京, Tōkyō^?, "Eastern Capital") [toːkʲoː], English /ˈtoʊki.oʊ/; officially Tokyo Metropolis (東京都, Tōkyō-to^?), is one of the 47 prefectures of Japan. Tokyo is the capital of Japan, the center of the Greater Tokyo Area, and the largest metropolitan area of the world. It is the seat of the Japanese government and the Imperial Palace, and the home of the Japanese Imperial Family. Tokyo is in the Kantō region on the southeastern side of the main island Honshu and includes the Izu Islands and Ogasawara Islands. Tokyo Metropolis was formed in 1943 from the merger of the former Tokyo Prefecture (東京府, Tōkyō-fu^?) and the city of Tokyo (東京市, Tōkyō-shi^?).

The Tokyo Metropolitan government administers the 23 special wards of Tokyo (each governed as a city), which cover the area that was the city of Tokyo, as well as 39 municipalities in the western part of the prefecture and the two outlying island chains. The population of the special wards is over 8 million people, with the total population of the prefecture exceeding 13 million. The prefecture is part of the world's most populous metropolitan area with upwards of 35 million people and the world's largest urban agglomeration economy with a GDP of US$1.479 trillion at purchasing power parity in 2008, ahead of New York City metropolitan area, which ranks second on the list. The city hosts 47 of the Fortune Global 500 companies, the highest amount of any city.
