Downstate New York is a term denoting the portion of New York State, United States, in contrast to Upstate New York, although the term "Downstate New York" has less currency than its counterpart term "Upstate New York". The Downstate region, like Upstate New York, is divided into several subregions: New York City and Long Island.
The Downstate region contains the largest population concentration in the state, unlike Upstate, an area which forms the vast majority of the state's land area yet has a smaller population. The two regions differ culturally and socially in terms of demographics, economy, and social patterns.
Like most other regions, there is no definitive or permanent boundary between Upstate and Downstate New York. Area residents often use Interstate 84 to delineate the boundary between upstate and downstate New York, although persons living further upstate generally consider the border with downstate to be further north than those who live downstate, and vice versa. As urban sprawl progressively converts rural communities into suburbs, many people increasingly consider neighboring Putnam County to be part of the Downstate region, as well as the southern portions of Orange County and Dutchess County. Furthermore, by 2010 the Metro-North Railroad surpassed the Long Island Rail Road in ridership as the busiest commuter line in the United States, for the first time in three decades, indicating a cultural shift in what would be considered the downstate area. 
One official usage of the term is by the State University of New York ("SUNY") system in the name of their southernmost medical school, SUNY Downstate Medical Center, located in East Flatbush, Brooklyn. The New York State Department of Transportation ("NYSDOT") also uses the term.
