Martha's Vineyard

Martha's Vineyard, often simply called the Vineyard, is an island in the Northeastern United States, south of Cape Cod in Dukes County, Massachusetts, known for being a popular, affluent summer colony. Martha's Vineyard includes the smaller adjacent Chappaquiddick Island, a peninsula, currently connected to the Vineyard. It is the 58th largest island in the U.S., with a land area of about 96 square miles, and the third-largest on the East Coast, after Long Island and Mount Desert Island. Martha's Vineyard constitutes the bulk of Dukes County, which also includes the Elizabeth Islands and the island of Nomans Land.

The island's year-round population has considerably increased since the 1960s. In the 2023 Martha’s Vineyard Commission report, the year-round population was 20,530, an increase from 16,460 in 2010. The summer population swells to more than 200,000 people.
