Granite Harbour () is a bay in the coast of Victoria Land, about 14 nautical miles (26 km) long, entered between Cape Archer and Cape Roberts. Discovered and named by the Discovery expedition (1901–04) in the Discovery in January 1902, while searching for safe winter quarters for the ship. The name derives from the great granite boulders found on its shores.
