Pittsburg County is a county located in the U.S. state of Oklahoma. As of the 2010 census, the population was 45,837. Its county seat is McAlester. The county was formed from part of the Choctaw Nation in Indian Territory in 1907. County leaders believed that its coal production compared favorably with Pittsburgh, Pennsylvania at the time of statehood.

Pittsburg County comprises the McAlester, OK Micropolitan Statistical Area.


The area forms the present Pittsburg county was part of the Choctaw Nation after the Choctaw tribe was forced to relocate to Indian Territory from its home in the Southeastern United States in the early 1830s. Some important trails, including the Texas Road and one route of the California Trail passed through it. In 1840, James Perry established a village called Perryville that became an important stop near the place where the two trails crossed. During the Civil War, Perryville served as an important supply depot for Confederate forces until the Union Army captured and burned the town. It became defunct after the Missouri, Kansas and Texas Railway (MK&T) bypassed it in 1872, and the remaining inhabitants moved to McAlester. The Butterfield Overland Mail route followed a route through this area.

James J. McAlester moved to the Choctaw Nation in 1872, opened a trading post and married a Chickasaw woman. This qualified him to obtain citizenship rights in the Choctaw and Chickasaw Nations. When the MK&T built its line, McAlester laid claim to the coal deposits in the Perryville area, which he and some partners leased to the Osage Coal and Mining Company, which was owned by the Missouri Pacific Railroad and acquired by the MK&T in 1888.

Pittsburg County was formed on July 16, 1907 as an original county from Choctaw land. County leaders, thinking its coal production compared favorably with Pittsburgh, Pennsylvania, was named the new county after the Pennsylvania city with the "h" removed. Coal mining continued to expand until the early 20th century. Production began to decline after 1920, and never fully recovered. By 1966, the county production was no longer reported.


According to the U.S. Census Bureau, the county has a total area of 1,378 square miles (3,570 km2), of which 1,305 square miles (3,380 km2) is land and 72 square miles (190 km2) (5.3%) is water. The county's topography is generally hilly to mountainous. The Ouachita Mountains extend into the southeastern portion. The Canadian River drains most of the county and with Eufaula Lake form the northern boundary of the county. The southern part of the county is drained by several creeks that flow into the Kiamichi River and then into the Red River.

Although Pittsburg county was originally noted for its coal production, agriculture has long been important to the county economy. Just after statehood, farmers controlled 20 percent of the county's land area. The most important cash crops were corn and cotton. By 1960, sorghum had become the most important crop. In 2000, wheat had become the top crop.

Manufacturing became significant when the U.S. Navy built an ammunition depot at McAlester during World War II. It employed 8,000 people in 1945. The U. S. Army took over the facility in 1977.

The Corps of Engineers built Eufaula Lake between 1956 and 1964, which brought tourism, land development and a major source of hydroelectric power.
