Gwinnett County is a county in the north central portion of the U.S. state of Georgia. As of 2018 , the population is estimated to be 927,781, making it the second-most populous county in Georgia. Its county seat is Lawrenceville. The county is named for Button Gwinnett, one of the signatories of the Declaration of Independence.
Gwinnett County is included in the Atlanta-Sandy Springs-Roswell, GA Metropolitan Statistical Area.
Created in 1818 by an act of the Georgia General Assembly, Gwinnett County was formed from parts of Jackson County (formerly part of Franklin County) and from lands gained through the cession of Creek Indian lands. Named for Button Gwinnett, one of the signatories of the Declaration of Independence, the first county election was held at the home of Elisha Winn, and the first Superior Court was held in his barn. The county seat was later placed at Lawrenceville.
In 1831 a group of white men were tried and found guilty in Lawrenceville for violating Georgia law by living in the Cherokee Nation without a valid passport from the Governor. Two of the men appealed to the US Supreme Court in Worcester v. Georgia, which resulted in a ruling stating that only the federal government had jurisdiction over native lands, a decision which still stands.
The Freedmen's Bureau was active in Gwinnett County during Reconstruction. In 1871 the courthouse in Lawrenceville was burned by the Ku Klux Klan in an attempt to avoid prosecution for their crimes, which included the shooting of a black election manager in Norcross.
In 1861, all three of Gwinnett County's representatives at the Georgia Constitutional Convention (1861) in Milledgeville voted against secession. Towards the end of the war, Union troops foraging in Gwinnett County as part of the Atlanta Campaign.
Early in the county's history, gold mining was a minor industry. The Gwinnett Manufacturing Company, a cotton textile factory, operated in Lawrenceville in the 1850s through 1865, when it burned. The Bona Allen Company in Buford, Georgia produced saddles, harnesses and other leather goods from 1873 to 1981.
The northeastern part of Gwinnett County was removed to form a part of the new Barrow County in 1914.
The southern and central portions of Gwinnett County are located in the Upper Ocmulgee River sub-basin of the Altamaha River basin. Most of the county's northern edge, from south of Peachtree Corners to north of Buford, is located in the Upper Chattahoochee River sub-basin of the ACF River Basin (Apalachicola-Chattahoochee-Flint River Basin). The county's eastern edge, north and south of Dacula, is located in the Upper Oconee River sub-basin of the same Altamaha River basin.
The county maintains a regional airport under the name Gwinnett County Airport, formerly Briscoe Field. The closest major airport serving the region is Hartsfield-Jackson Atlanta International Airport.
Interstate 285 (while not inside the county) is roughly 1.5 miles from the county line.
In 2016, Suwanee unveiled the first Bike Share program in Gwinnett County.

Gwinnett County, Georgia is governed by a five-member Board of Commissioners, which exercises both legislative and executive authority within the county. The chairman of the board is elected county-wide and serves full-time. The four other commissioners are elected from single-member districts and serve part-time positions. The board hires a county administrator who oversees daily operations of the county's twelve executive departments. Gwinnett County has a police department that operates under the authority of the Board of Commissioners. Some of the local Gwinnett city budgets have recently come under increasing scrutiny of the General Funds allocated to police services. Cities such as Duluth have allocated as much as forty percent of their city budgets, reaching some of the highest levels in the nation. Solutions to high spending being discussed include additional "investment in mental health, housing, youth development and living wages would stabilize communities and prove more effective than policing."
In addition to the Board of Commissioners, county residents also elect persons to the following positions: Sheriff, District Attorney, Probate Court Judge, Clerk of State/Superior Court, Tax Commissioner, State Court Solicitor, Chief Magistrate Judge (who appoints other Magistrate Court judges), Chief Superior Court Judge and Superior Court Judges, and Chief State Court Judge and State Court Judges.
Gwinnett County has the largest public school system in the state of Georgia. Members of the Board of Education are elected from special election districts in the county.
From 1980 until 2012, the county was a Republican stronghold in presidential elections, which has since changed in recent times as the county has gotten larger and more diverse. In 2016, Hillary Clinton became the first Democrat to win Gwinnett County since 1976, when Georgia native Jimmy Carter won every county in the state. In 2018, Stacey Abrams became the first Democrat to win Gwinnett County in a gubernatorial election since 1986 when Joe Frank Harris swept every county statewide.
