Greer County is a county located along the southwest border of the U.S. state of Oklahoma. As of the 2010 census, the population was 6,239. Its county seat is Mangum. From 1860 to 1896, the state of Texas claimed an area known as Greer County, Texas, which included present-day Greer County along with neighboring areas. In 1896 it was designated as a county in Oklahoma Territory under a ruling by the US Supreme Court. The rural Greer County is home to Quartz Mountain Nature Park, near the community of Lone Wolf, Oklahoma (known until 2002 as Quartz Mountain State Park). It is also home to the Oklahoma State Reformatory, located in Granite. Its population has declined since 1930 due to changes in agriculture and migration to cities for work.
After a dispute over the 1819 Adams-Onís Treaty and the related 1828 Treaty of Limits, the governments of both the United States and the state of Texas claimed ownership of some 1.5 million acres (6,000 km2) in what was then operated as Greer County, Texas. The county was named for former Texas lieutenant governor, John A. Greer. Litigation followed, and in the case of United States v. State of Texas 162 U.S. 1 (1896), with a ruling issued on March 16, the Supreme Court, having original jurisdiction over the case, decided in favor of the United States.
The county was assigned to the Oklahoma Territory on May 4, 1896. When Oklahoma was admitted as a state, Greer County was established according to its current boundaries; the remaining former county area was organized as Harmon, Jackson, and part of Beckham counties. The town of Mangum, designated as the county seat in 1886 when this was part of Texas, continued as the seat of Greer County, Oklahoma. From its establishment until at least 1903, Greer County was a sundown county, prohibiting African Americans from living in the county.
Originally developed for agriculture, the rural county had its peak of population in 1930. Mechanization of agriculture reduced the need for farm labor, and the population has declined as people migrated to cities for work.
Among the county attractions is Quartz Mountain Nature Park (known until 2002 as Quartz Mountain State Park), near the community of Lone Wolf.
According to the U.S. Census Bureau, the county has a total area of 644 square miles (1,670 km2), of which 639 square miles (1,660 km2) is land and 4.3 square miles (11 km2) (0.7%) is water.
Western Greer County lies in the Gypsum Hills, while the eastern one-third is in the Red Bed Plains physiographic region. The county is drained by the North Fork Red River, Elm Fork Red River, and Salt Fork Red River.

Because the ban has been placed on the negroes by the citizens of Greer county, Okla., there will be an estimated loss of 5,000 bales of this year's cotton crop. Greer county, which, until a few years ago, was a part of Texas, is one of the big cotton producers of the territory. This year the farmers raised 20 per cent. increased acreage and a 15-per-cent. increase yield, but there is a labor famine. The growers have been threatened by the citizens in general upon every attempt to import negroes, but unless the necessary laborers are secured in the immediate future the financial loss will be great. The growers now have a movement on foot to bring 100 Mexican families to pick the cotton crop. Since the organization of Greer county no negroes have been allowed to live within its boundaries.
