Plum Island is an island in Lake Michigan in the southern part of the town of Washington in Door County, off the tip of the Door Peninsula in the U.S. state of Wisconsin. The uninhabited island has a land area of 1.179 square kilometres (0.455 sq mi) or 117.87 hectares (291.3 acres). The island is a bird sanctuary under control of the United States Fish and Wildlife Service and part of the Green Bay National Wildlife Refuge. The island also holds the unmanned Plum Island Range Lights. There are an estimated 250 shipwrecks off the island's shores.

History

The border between Wisconsin and Michigan was originally defined as "the most usual ship channel" into Green Bay from Lake Michigan but commercial routes existed both to the north and south of the island which led to a border dispute. In 1936, the U.S. Supreme Court decision Wisconsin v. Michigan found that Plum and three other islands were part of Wisconsin.
