John Calvin Smith (poss. 1809 – June 11, 1890) was an American surveyor and geographer active in New York during the middle part of the 19th century. He was a charter member of the American Geographical and Statistical Society (American Geographical Society). He worked with other important New York cartographers including John Disturnell, George Sherman, and Samuel Stiles, with whom he often published under the Stiles, Sherman & Smith imprint. Stiles may have introduced Smith to J. H. Colton, who acquired many of his map plates in 1853. Despite being an important and prolific cartographer, much of his personal life and history are shrouded in mystery.
