Is New Jersey a Peninsula?

According to the New Jersey Environmental Health Association, New Jersey is a peninsula. New Jersey is separated on its west and south sides from Delaware and Pennsylvania by the Delaware Bay and Delaware River.

On the east side of New Jersey, the perimeter is provided by the Atlantic Ocean, New York Bay, Kill van Kull, the Hudson River and Arthur Kill. New Jersey got its name from the "Isle of Jersey," which was a British Crown Dependency off the coast of Normandy, France, in the English Channel. Another interesting fact is that from Maine to Florida, throughout the entire eastern seaboard, Highlands, New Jersey, has the highest elevation.
