Nolan County is a county located in the west central region of the U.S. state of Texas. As of the 2010 census, its population was 15,216.  Its county seat is Sweetwater.  The county was created in 1876 and organized in 1881.  It is named for Philip Nolan, one of the first American traders to visit Texas.
Nolan County comprises the Sweetwater, TX Micropolitan Statistical Area.
From 1921 to 1925, the Democrat Richard M. Chitwood of Sweetwater represented Nolan County in the state House. As chairman of the House Education Committee, he worked in 1923 to establish what became Texas Tech University in Lubbock. He had first tried to obtain the institution for Sweetwater as the central location of West Texas. After the institution was established, he resigned from the House to move to Lubbock to become the first Texas Tech business manager. He served in that capacity for just 15 months; he died in Dallas in November 1926. 
According to the U.S. Census Bureau, the county has a total area of 914 square miles (2,370 km2), of which 912 square miles (2,360 km2) are land and 2.0 square miles (5.2 km2) (0.2%) are covered by water. 
Nolan County is in the Cross Timbers region for wildlife management.  Geologically Nolan County occupies part of the Rolling Plains in the North and South,  separated by an isolated part of the Edwards Plateau  in much of the center. The uplifted plateau, rising up to 500  feet above the surrounding plains, gives Nolan county an advantage on production of wind energy.
