Humphrey Phelps (1799 - 1875) was an American map, broadside, and book publisher based in New York City. He worked independently as well as in partnership with Ensign and Thayer. Phelps was born in 1799 in Hebron, Connecticut. Phelps' earliest work seems to be a plan of New York City for his Stranger's Guide, dating to about 1830. The New York map publishing circle seems to have been quite close and Phelps commonly partnered with various other New York publishers and printers including Edward H. Ensign (1818 - 1871), Horace Thayer, Erastus Clark Bridgman (1817 - 1870), Thomas C. Fanning (1805 - 1873), Hooker, Peabody, Charles Magnus, Gaylord Watson, and George Walker, among others. The natural consequence of his rampant partnering is a vast and varied corpus of work including many scarce items with low print runs. Phelps is best known for his emigrant and tourist guides.
