Martha's Vineyard (adjoining the smaller Chappaquiddick Island) is an island off the United States east coast, to the south of Cape Cod, both forming a part of the Outer Lands region. It is often called just "the Vineyard". With a land area of 87.48 square miles (231.75 km²), Martha's Vineyard is the 57th largest island in the United States and third largest on the eastern seaboard.

It is located in the U.S. state of Massachusetts, in Dukes County, which also includes Cuttyhunk and the other Elizabeth Islands, as well as the island of Nomans Land). It was home to one of the earliest known deaf communities in the United States; consequently, a special dialect of sign language, Martha's Vineyard Sign Language, developed on the island.

The island is primarily known as a summer colony, and is accessible only by boat and by air. Nevertheless, its year-round population has grown considerably since the 1960s. A study by the Martha's Vineyard Commission found that the cost of living on the island is 60 percent higher than the national average and housing prices are 96 percent higher.
