• Connecticut – east, across Long Island Sound
• Massachusetts – east
• New Hampshire – northeast (short border)
• Vermont – east, along Lake Champlain
• Pennsylvania – south
• New Jersey – south, across the Hudson River

International Border

To the north and northwest, New York borders the Canadian provinces of Quebec and Ontario, with the St. Lawrence River and Lake Ontario forming much of the boundary.
