Spinnaker Island (formerly known as Park Island, Hog Island, and Little Hog Island) is an island in the Hingham Bay area of Boston Harbor in Massachusetts, USA. The island is part of the town of Hull, to which it is connected by a bridge, and is one of the few harbor islands that neither forms part of the Boston Harbor Islands National Recreation Area nor is considered within the municipal limits of the city of Boston.
