Dade County is a county in the U.S. state of Georgia. It occupies the northwest corner of Georgia, and the county's own northwest corner is the westernmost point in the state. As of the 2020 census, the population is 16,251. The county seat and only incorporated municipality is Trenton. Dade County is part of the Chattanooga, TN–GA Metropolitan Statistical Area. In 1860, residents of Dade County voted to secede from the state of Georgia and from the United States, but no government outside the county ever recognized this gesture as legal. In 1945, the county symbolically "rejoined" Georgia and the United States.
