History
Green Hill was first settled before 1800 by John Cloyd and John Williamson, who moved their families to the area from Nashville to escape a smallpox outbreak. Colonel John Donelson, Jr., later established a summer home at Green Hill. The community's name may be a description of the location or may honor a former state treasurer of North Carolina.

During the 19th century, Green Hill was the site of a post office, established in 1834 or 1838 and closed in 1904.

Shortly before the outbreak of the Civil War, Green Hill supported a high school. Businesses included a general store, a hotel, a tobacco processor, a flour mill, and a carding machine. A high school was opened at the junction of Lebanon Road and North Greenhill Road in August 2020.
