Connecticut is the southernmost state in the New England region of the northeastern United States. It is bordered by Rhode Island to the east, Massachusetts to the north, New York to the west, and Long Island Sound to the south. Geographically the state is part of New England, and although its cultural history stems from the region, in the modern age large sections of it are increasingly connected to and associated with the tri-state area with New York and New Jersey.
