Suffolk County is the easternmost county in the U.S. state of New York. It is mainly located on the eastern end of Long Island, however there are several islands that are also part of Suffolk County. According to the 2020 United States census, the county's population was 1,525,920 making it the fourth-most populous county in New York State, after New York City's Brooklyn, Queens, and Manhattan. Its county seat is Riverhead, though most county offices are in Hauppauge. The county was named after the county of Suffolk in England, from where its earliest European settlers came.
Suffolk County incorporates the easternmost extreme of the New York City metropolitan area. The geographically largest of Long Island's four counties and the second-largest of 62 counties in New York State, Suffolk measures 86 miles (138 km) in length and 26 miles (42 km) in width at its widest (including water). Most of the island is near sea level, with over 1,000 miles of coastline.
Like other parts of Long Island, the high population density and relative closeness to New York City means that the economy has a mix of industry and science satellite to the city alongside more rural activities like agriculture, a fishery and tourism. Major scientific research facilities in Suffolk County include Brookhaven National Laboratory in Upton, Cold Spring Harbor Laboratory in Huntington, and Plum Island Animal Disease Center on Plum Island. The county is also home to several major universities such as Stony Brook University and Farmingdale State College.

Suffolk County was an original county of the Province of New York, one of twelve created in 1683. From 1664 until 1683 it had been the East Riding of Yorkshire. Its boundaries were essentially the same as at present, with only minor changes in the boundary with its western neighbor, which was originally Queens County but has been Nassau County since the separation of Nassau from Queens in 1899.
According to the Suffolk County website, the county is the leading agricultural county in the state of New York, saying that: "The weather is temperate, clean water is abundant, and the soil is so good that Suffolk is the leading agricultural county in New York State. That Suffolk is still number one in farming, even with the development that has taken place, is a tribute to thoughtful planning, along with the excellent soil, favorable weather conditions, and the work of dedicated farmers in this region."
According to the U.S. Census Bureau, the county has a total area of 2,373 square miles (6,150 km2), of which 912 square miles (2,360 km2) is land and 1,461 square miles (3,780 km2) (62%) is water. It is the second-largest county in New York by total area and occupies 66% of the land area of Long Island.
Suffolk County occupies the central and eastern part of Long Island, in the extreme east of New York State. The eastern end of the county splits into two peninsulas, known as the North Fork and the South Fork. The county is surrounded by water on three sides, including the Atlantic Ocean and Long Island Sound, with 980 miles (1,580 km) of coastline. The eastern end contains large bays.

At various times, there have been proposals for a division of Suffolk County into two counties. The western portion would be called Suffolk County, while the eastern portion of the current Suffolk County would comprise a new county to be called Peconic County. Peconic County would consist of the five easternmost towns of Suffolk County: East Hampton, Riverhead, Shelter Island, Southampton and Southold, plus the Shinnecock Indian Reservation.
The proposed Peconic County flag showed the two forks at the east end of Long Island separated by Peconic Bay. The star on the north represents Southold. The stars on the South Fork represent Southampton and East Hampton. Riverhead is at the fork mouth and Shelter Island is between the forks.
The secessionist movement has not been active since 1998.
The End of the Hamptons: Scenes from the Class Struggle in America's Paradise, by Corey Dolgon (New York University Press, 2005) examined the class roots of the secessionist movement in the Hamptons. In his review, Howard Zinn wrote that the book "[t]akes us beyond the much-romanticized beaches of Long Island to the rich entrepreneurs and their McMansions, the Latino workers, and the stubborn indigenous residents refusing to disappear. The book is important because it is in so many ways a microcosm of the nation." The book won the Association for Humanist Sociology's 2005 Book Prize and the American Sociological Association's Marxist Section Book Award in 2007.
In New York State, a town is the major subdivision of each county. Towns provide or arrange for most municipal services for residents of hamlets and selected services for residents of villages. All residents of New York who do not live in a city or on an Indian reservation live in a town. A village is an incorporated area which is usually, but not always, within a single town. A village is a clearly defined municipality that provides the services closest to the residents, such as garbage collection, street and highway maintenance, street lighting and building codes. Some villages provide their own police and other optional services. A hamlet is an informally-defined populated area within a town that is not part of a village.
