Edmund March Blunt (June 20, 1770 – January 4, 1862) was an American navigator, writer, and publisher of nautical magazines.

In 1796, Blunt sold his interest in the paper to Angier March who continued the publication until it was merged with the Political Gazette in 1797 when the name changed to the Newburyport Herald.

[9][10] When Blunt sold the Impartial Herald, he published the American Coast Pilot in 1796, in Newburyport, Massachusetts.

[4] By 1815, Blunt had moved to New York where he opened a place of business at 202 Water Street, Beekman Slip, New York, "where charts and pilots for every part of the world, nautical books of every description, sextants, circles, quadrants, spy glasses, compasses and every nautical and mathematical instruments requisite at sea may be had on the most reasonable terms.

[5][6] The firm closed in 1872 and sold the chart copyrights and plates to the Coast Survey and U.S. Navy Hydrographic Office.
