Cornelius Island is a small uninhabited island in Wickford Harbor, Narragansett Bay, Wickford, Rhode Island.
The land compromising Cornelius Island was originally connected to the mainland and was part of the Smith/Updike land holdings until it was sold in 1813. A channel was dug at some point in the land's history disconnecting it from the mainland. It is unclear after whom Cornelius Island was named.[1] The island was used in the 1960s for the deposition of dredged material.
