Hidden Lake (64°2′S 58°18′W) is a lake, 1.5 nautical miles (3 km) long, lying midway between Lagrelius Point and Cape Obelisk in the western part of James Ross Island. It drains by a small stream into the deep bay 4 nautical miles (7 km) south of Lagrelius Point. It was discovered in 1945 by the Falkland Islands Dependencies Survey, who so named it because it is obscured by surrounding highlands.
