The Town of Oak Bluffs is a resort town on the northeast shore of the island of Martha's Vineyard, Massachusetts. Originally incorporated in 1880 as Cottage City, in 1907 the town's name was changed because of the growth in the year round population and the changing face of the resort required an acknowledgement the town was not just "Cottage City" any more.

Oak Bluffs operates the largest marina on Martha's Vineyard, which not only has the most slips, but is situated in the midst of the historic gingerbread campgrounds, and offers easy access to the rest of the Island. "OB," as it is sometimes referred to, also is home to several beautiful public beaches; a teeming shore of wildlife, fish and shellfish; fabulous public parks; a golf course; and even a microbrewery!
