Russell Island is a small private island in the St. Clair River in the U.S. state of Michigan between Algonac and Walpole Island, Ontario, Canada. It is immediately upriver from Harsens Island, of which it can be considered the uppermost extension, and includes two smaller islands, Anderson Island on the northwest, and "The Gold Coast" on the southwest. The island, which is accessible only via the Russell Island Ferry or by private watercraft, contains about 150 cottages. There are no cars on the island; the only motorized vehicles are golf carts.
