The Massachusetts Bay Colony was an English settlement on the east coast of North America (Massachusetts Bay) in the 17th century. The settlement was located in New England, situated around the present-day cities of Salem and Boston. The territory administered by the colony included much of present-day central New England, including portions of the U.S. states of Massachusetts, Maine, New Hampshire, Rhode Island, and Connecticut. Territory claimed but never administered by the colonial government extended as far west as the Pacific Ocean.
