Greensboro is a city in and the county seat of Guilford County, North Carolina, United States. It is the third-most populous city in North Carolina, the 68th-most populous city in the United States, and the largest city in the Piedmont Triad metropolitan region. At the 2020 United States census, its population was 299,035. Three major interstate highways in the Piedmont region of central North Carolina were built to intersect at this city.
In 1808, Greensborough was planned around a central courthouse square to succeed Guilford Court House as the county seat. The county courts were thus placed closer to the county's geographical center, a location more easily reached at the time by the majority of the county's citizens, who traveled by horse or on foot.
In 2003, the previous Greensboro–Winston-Salem–High Point metropolitan statistical area was redefined by the U.S. Office of Management and Budget. The region was separated into the Greensboro–High Point metropolitan area and the Winston-Salem metropolitan area. The 2010 population of the Greensboro–High Point metropolis was 723,801.
