There are or have been several movements regarding secession in the U.S. state of New York.
The most prominent amongst these have been for a state called Long Island, consisting of everything on the island outside New York City; a state called Niagara, the western counties of New York state; the northern counties of New York state called Upstate New York; making the city of New York a state; a proposal for a new Peconic County on eastern Long Island; and for the boroughs of Staten Island and Brooklyn to secede from New York City.
Thought I checked for a NY post...missed by the time I was typing, I guess.
