James H. Young (fl. c. 1817 - 1866) was an Irish-American draughtsman, engraver, and cartographer active in Philadelphia during the first half of the 19th century. Young engraved for numerous cartographic publishers in the Philadelphia area, including Anthony Finley, Charles Varle, William Kneass, Delleker, and Samuel Augustus Mitchell, among others. His most significant work includes the maps for Finley and later Mitchell's New American Atlas. Mitchell proved to be Young's most significant collaborator. The pair published numerous maps from about 1834 well into the 1860s. In 1840 he registered a patent for an improved system of setting up typography for printing. Unfortunately little has been discovered regarding his personal life.
