Chung-Tung Litho Works (中东石印局民国, 1912 - c. 1930) was a lithographic printer based in the concession city of Tientsin or Tianjin, China, during the early 20th century. The rise of the Chung-Tung Litho works roughly coincides with the establishment of the Beiyang Government in 1912 and the fall of said government in 1929. Their corpus is small, including a map of Tientsin (1912), reissued multiple times, and a 1914 map of Beijing, but the quality of their work was extremely high. Most of their maps are chromolithographs, making them one of the earliest Chinese chromolithographic presses in Asia.
