New Jersey's Borders: Neighboring States and Water Boundaries

The State of New Jersey is bordered by:

• New York – to the north and northeast (land and water boundaries, including the Hudson River).
• Pennsylvania – to the west (defined by the Delaware River).
• Delaware – to the southwest (across the Delaware Bay).
• Atlantic Ocean – to the southeast and south (130 miles of coastline).

New Jersey is the only U.S. state where every county is classified as "urban" by the Census Bureau, and its dense population is shaped by this compact, strategically located geography between New York and Philadelphia.
