Burlington County is located east of the Delaware River and borders Philadelphia, the nation's sixth-largest city. It is part of the Philadelphia-Camden-Vineland, PA-NJ-DE-MD combined statistical area, also known as the Delaware Valley. However, the county stretches across the state, and its southeast corner reaches tidal estuaries leading to New Jersey's Great Bay, which separates the county from the Atlantic Ocean.
