CSS Savannah, later called Old Savannah and Oconee, was a gunboat in the Confederate States Navy during the American Civil War. Savannah was formerly the steamer Everglade, built in 1856 at New York City. She was purchased early in 1861 by the State of Georgia and converted into a gunboat for coast defense. With Georgia's admission to the Confederacy, Savannah, under Lieutenant John Newland Maffitt, was commissioned by the Confederate States Navy. She was attached to the squadron of Flag Officer Josiah Tattnall, charged with the naval defense of South Carolina and Georgia.
