High Island is an island in Lake Michigan and is part of the Beaver Island archipelago. It is in size. The island is owned by the U.S. state of Michigan and is managed by the Michigan Department of Natural Resources as part of the Beaver Islands State Wildlife Management Area.
High Island got its name from a large, perched sand dune on the western side of the island. The sand, blown by the lake's prevailing winds, has piled up into a sand dune elevated 780 feet (238 m) above sea level, or 199 feet (61 m) above the level of Lake Michigan.
The island is currently uninhabited. It lies approximately four miles (6 km) west of the much larger Beaver Island.
