Herald Island (Russian: Остров Геральд, Ostrov Gerald) is a small, isolated Russian island in the Chukchi Sea, 70 km (43 mi) to the east of Wrangel Island. It rises in sheer cliffs, making it quite inaccessible, either by ship or by plane. The only sliver of shoreline is at its northwestern point, where the cliffs have crumbled into piles of loose rocks and gravel. Its area is 11.3 km² (4.36 sq mi) and the maximum height above sea level is 364 m (1,194 ft). The island is unglaciated and uninhabited.
