Oak Ridge is a town in northwestern Guilford County, North Carolina, United States. The population was 6,185 at the 2010 census, up from 3,988 at the 2000 census. As of 2018 the population had risen to an estimated 6,977. Oak Ridge is 15 miles (24 km) northwest of the center of Greensboro, North Carolina's third-largest city, and it is a part of the Piedmont Triad urban area.
The town is home to Oak Ridge Military Academy, a private, co-educational, college-preparatory military boarding school. Founded in 1852, it is the third-oldest military school in the nation still in operation, and it is the official military school of North Carolina, as designated by the state legislature.
Until the late 1990s, the Oak Ridge area was mostly rural farmland with numerous tobacco farms. However, since its incorporation as a town in 1998, Oak Ridge has seen rapid growth in its population. Many of the area's farms have been sold to developers and turned into upper-class housing developments, and several shopping centers have been built along the NC 68 corridor, especially at its intersection with Oak Ridge Road (NC 150), near the military academy.
Each Easter weekend from 1945 to 2013, the community hosted a popular horse show.
The Jesse Benbow House II, Guilford Mill, and Oak Ridge Military Academy Historic District are listed on the National Register of Historic Places.
Oak Ridge is located in northwestern Guilford County at 36°10′1″N 79°58′57″W (36.166944, -79.982577).
