The John Stephenson Car Company was an American manufacturer of carriages, horsecars, cable cars, and streetcars, based in New York City. It was founded by John Stephenson in 1831. John Stephenson invented the first streetcar to run on rails, building this in 1832, for the New York and Harlem Railroad. A reorganization in 1867 included shortening of the company's name to the John Stephenson Company. In the latter part of the 19th century, the company was a major builder of streetcars, constructing some 25,000 cars in the period 1876–1891 alone, including ones for export.
