Joseph Dennie (August 30, 1768 – January 7, 1812) was an American author and journalist who was one of the foremost men of letters of the Federalist Era. A Federalist, Dennie is best remembered for his series of essays entitled The Lay Preacher and as the founding editor of The Port Folio, a journal espousing classical republican values. Port Folio was the most highly regarded and successful literary publication of its time, and the first important political and literary journal in the United States. Timothy Dwight IV once referred to Dennie as "the Addison of America" and "the father of American Belles-Lettres."
