USS Polaris, originally called the America, was an 1864-screw steamer procured by the Union Navy as USS Periwinkle during the final months of the American Civil War. She served the Union Navy's struggle against the Confederate States as a gunboat.
After the war, the ship was retained by the U.S. Navy. She was renamed Polaris in 1871 and became the designated vessel of the Hall scientific expedition to the North Pole. It was on this voyage that she proceeded into Arctic waters, only to have her hull crushed by the ice in October 1872.
