Millbourne Mills was a flour mill owned by the Sellers family in Upper Darby Township, Pennsylvania, U.S.A., as well as the name of a former railroad station located there. The Pennsylvania Railroad's Cardington Branch ended there, where interchange was made with the Philadelphia and Western Railroad. Deliveries were also made to the Philadelphia and West Chester Traction Company and to the Philadelphia Rapid Transit Company. No interchange of cars was possible with the latter two railroads due to the difference in rail gauge.
