The Brooklyn and Queens Transit Corporation (B&QT) was a subsidiary of the Brooklyn–Manhattan Transit Corporation that operated streetcars in Brooklyn and Queens, New York City, United States (as well as into Manhattan via the Brooklyn Bridge and Williamsburg Bridge). It was created in 1929 to operate these routes, which had previously been operated by the BMT directly; its operations were transferred to the New York City Board of Transportation in 1940, and to the New York City Transit Authority in 1956.
