About Delaware State Map

Delaware Map: Delaware is a state in the Mid-Atlantic area of the United States. The state is bordered by Maryland to the south and west, Pennsylvania to the north, New Jersey to the east, and the Atlantic Ocean to the west. The state is named from the nearby Delaware Bay, which was named after Thomas West, 3rd Baron De La Warr, an English nobleman and Virginia's first colonial governor. Delaware is located in the northeastern corner of the Delmarva Peninsula, as well as on a few islands and in certain areas of the Delaware River. Although it is the sixth-least populous and second-smallest state, it is also the sixth most densely populated. Wilmington is the largest city in Delaware, and Dover, the second-largest city, serves as the state's capital. Delaware Map shows these two cities as well as others.
