(c.1727–1813), New York printer and publisher, in 1776 founded The New York Packet and the American Advertiser, a patriotic weekly newspaper. Although a staunch patriot, he became unpopular with the radical element when he issued The Deceiver Unmasked; or, Loyalty and Interest United (1776), an anonymous reply to Paine's Common Sense. While the British occupied New York, the Packet was suspended (Aug. 1776–Jan. 1777). It was then resumed irregularly in Fishkill, N.Y., until Loudon could return to the city. In 1787–88 the paper printed many of the Federalist essays. After 1792 it was known as the Diary or Loudon's Register, under which title it was continued by his son.
