David Porter (February 1, 1780 – March 3, 1843) was an officer in the United States Navy in the rank of captain and the honorary title of commodore. Porter commanded a number of U.S. naval ships. He saw service in the First Barbary War, the War of 1812 and in the West Indies. On July 2, 1812, Porter hoisted the banner "Free trade and sailors' rights" as captain of USS Essex. The phrase resonated with many Americans. Porter was later court martialed; he resigned and then joined and became commander-in-chief of the Mexican Navy. Porter County, Indiana was named after him.
