The county borders the Atlantic Ocean on the east and in terms of total area is the state's largest county. Its county seat is Toms River.

The Jersey Shore, commonly referred to locally as simply the Shore, is the coastal region of the U.S. state of New Jersey. Geographically, the term encompasses about 141 miles (227 km) of oceanfront bordering the Atlantic Ocean, from Perth Amboy in the north to Cape May Point in the south. The region includes Middlesex, Monmouth, Ocean, Atlantic, and Cape May counties, which are in the central and southern parts of the state. Located in the center of the Northeast Megalopolis, the northern half of the shore region is part of the New York metropolitan area, while the southern half of the shore region is part of the Philadelphia metropolitan area, also known as the Delaware Valley. The Jersey Shore hosts the highest concentration of oceanside boardwalks in the United States.
