Jamestown Island is a 1,561-acre (632 ha; 2.439 sq mi) island in the James River in Virginia, part of James City County. It is located off Glasshouse Point, to which it is connected via a causeway. Much of the island is wetland, including both swamp and marsh.

In 1607, the Jamestown Island (then a peninsula) became site of Jamestown, the first permanent English settlement in the Americas. The town lasted until 1699, when it was abandoned in favor of a new site at Williamsburg. By the early 20th century, the isthmus connecting the landform to Glasshouse Point had eroded, making it a proper island. Today, most of the island is a part of Colonial National Historical Park.
