The Yokohama City Transportation Bureau, legally the Transportation Bureau, City of Yokohama (横浜市交通局, Yokohama-shi Kōtsū-kyoku) is the local government administrative agency in charge of public transport services in the city of Yokohama, Japan.

At 40.4 km, this is the second-longest subway in Japan after the Toei Ōedo Line in Tokyo.

Although it runs entirely underground, the Minatomirai Line is not considered part of the subway network, and is not administered by the Transportation Bureau, but by the Yokohama Minatomirai Railway Company.
