About Dukes County
Dukes County, Massachusetts, is a unique island county comprising Martha's Vineyard and the Elizabeth Islands, located off the southern coast of Cape Cod. Established in 1683 and named after the Duke of York (later King James II), it is one of the smallest counties in Massachusetts by land area, covering approximately 104 square miles of land and over 260 square miles when including water. The county seat is Edgartown, one of six towns on Martha's Vineyard: Edgartown, Oak Bluffs, Tisbury (Vineyard Haven), West Tisbury, Chilmark, and Aquinnah (formerly Gay Head).
According to recent census estimates, Dukes County has a year-round population of approximately 17,000-20,000 residents, which swells dramatically during summer months to over 100,000 with seasonal visitors and second-homeowners. Major landmarks include the Gay Head Cliffs (Aquinnah Cliffs), a National Natural Landmark with striking multicolored clay formations; the historic Edgartown Lighthouse; the Victorian-era gingerbread cottages of Oak Bluffs' Martha's Vineyard Camp Meeting Association; and the picturesque harbors throughout the island. The Dukes County Registry of Deeds, located at 81 Main Street in Edgartown, maintains land records for the county.
The Dukes County Clerk's Office operates from the Superior Courthouse at 81 Main Street, Edgartown, MA 02539. The county assessor functions are handled by individual town assessors in each county. What makes Dukes County truly unique is its island geography, accessible only by ferry or air, its role as a historic whaling center, its prominence as a presidential vacation destination, and its blend of working maritime communities, conservation land (nearly half the island is permanently protected), and summer resort culture.
