Amos Kendall (August 16, 1789 – November 12, 1869) was an American lawyer, journalist and politician. He rose to prominence as editor-in-chief of the Argus of Western America, an influential newspaper in Frankfort, the capital of the U.S. state of Kentucky. He used his newspaper, writing skills, and extensive political contacts to build the Democratic Party into a national political power. An ardent supporter of Andrew Jackson, he served as United States Postmaster General during the Jackson administration as well as briefly under Martin Van Buren. He was one of the most influential members of Jackson's "Kitchen Cabinet", an unofficial group of Jackson's top appointees and advisors who set administration policy. Returning to private life, Kendall invested heavily in Samuel Morse's new invention, the telegraph. He became one of the most important figures in the transformation of the American news media in the 19th century.
