Barnegat Bay is a small brackish arm of the Atlantic Ocean, approximately 30 miles (50 km) long, along the coast of Ocean County, New Jersey in the United States. It is essentially a long estuary formed by Barnegat Peninsula, a long barrier peninsula, as well as by the north end of Long Beach Island. The bay is fed by several small rivers, including the Toms River and Metedeconk River, which empty into the bay through small estuaries along its inner shore. The communities of Toms River, Silverton, and Forked River sit along the river estuaries on the bay.
