The following is a description of
islands in the Detroit River. The
Detroit River is a river in the
Great Lakes system, about 32 miles (51 km) long and 0.5–2.5 miles (0.8–4.0 km) wide. The river serves as a major shipping channel, jointly controlled by the
United States and
Canada, and is a major component of the
Canada–United States border. Ownership and control of the islands varies by their geographic location along the river. The majority of islands are on the American side of the river, which are all under the jurisdiction of
Wayne County in
Michigan. The Canadian islands are part of
Essex County in
Ontario. There are no islands in the Detroit River that are divided by the international border.
