Cape May consists of a peninsula and barrier island system in the U.S. state of New Jersey. It is roughly coterminous with Cape May County and runs southwards from the New Jersey mainland, separating Delaware Bay from the Atlantic Ocean. The southernmost point in both New Jersey and the northeastern United States lies on the cape. A number of resort communities line the Atlantic side of the cape, including Ocean City, the most populous community on the cape, The Wildwoods, known for its architecturally significant hotel district, and the city of Cape May, which has served as a resort community since the mid-1700s, making it the oldest such resort in the U.S.

Delaware Bay is the estuary outlet of the Delaware River on the northeast seaboard of the United States, lying between the states of Delaware and New Jersey. It is approximately 782 square miles (2,030 km2) in area, the bay's freshwater mixes for many miles with the saltwater of the Atlantic Ocean.
