Fleetwing was a schooner that sank in Lake Michigan off Liberty Grove, Wisconsin, United States.

On September 26, 1888, Fleetwing departed Menominee, Michigan, bound for Chicago, Illinois, with a cargo of lumber.

[3] Later that night, as the ship approached Porte des Morts, a gale began to form.

Reports of what happened later conflict, but what is known is that at 11:00 p.m., the ship struck a rocky beach that apparently sheared off a mast.

Initially, efforts were made to save the vessel, but another gale began to form during the process and the tugboat that had been attempting to retrieve Fleetwing was forced to leave the area.
