The Nantucket was a sidewheel steamer operating as a ferry serving the islands of Martha's Vineyard and Nantucket during the end of the nineteenth century and the beginning of the twentieth century. On the Vineyard it docked at Cottage City (later Oak Bluffs, Massachusetts), Vineyard Haven, and the West Chop Wharf. The Nantucket, a 629-ton vessel, was built in 1886 in Wilmington, Delaware for service with the New Bedford, Martha's Vineyard, and Nantucket Steamboat Co. fleet, later reorganized as the Steamship Authority.
