Gull Island, located in St. James Township, Charlevoix County, Michigan, is the largest of approximately one dozen islands bearing this name in Michigan.

Balsam fir and northern whitecedar grow in the island's humid, boreal climate.

Gull Island also has beaches and sand dunes on its north and east sides.

On November 18, 1958, the SS Carl D. Bradley, a cargo vessel that specialized in the transport of limestone for steel mills, foundered and sank 12 miles southwest of Gull Island.

The incident included the loss of 33 of the 35 men aboard.
