Carnegie (//) is a borough in Allegheny County, Pennsylvania, United States, and is part of the Pittsburgh metropolitan area. The population was 7,972 in the 2010 census.
Carnegie is located at. It is approximately 5 miles (8 km) southwest of Pittsburgh. Chartiers Creek runs through the center of the borough and one tributary, Campbells Run, joins Chartiers Creek here.
According to the United States Census Bureau, the borough has a total area of 1.6 square miles (4.1 km2), all of it land. Its average elevation is 833 ft (254 m) above sea level.
Carnegie has four borders, including Rosslyn Farms to the north, Scott Township to the east, south and southwest, Collier Township to the west, and Robinson Township to the northwest.
Carnegie is named after Andrew Carnegie, who donated one of his libraries for the gesture. It was incorporated on March 1, 1894, from the boroughs of Chartiers and Mansfield (separated by Chartiers Creek). Later, the borough annexed part of Robinson Township (now Rosslyn Heights). Neighborhoods include Rosslyn Heights, Cubbage Hill, Irishtown, Forsythe Hill, Library Hill, and Old Mansfield.
Many neighborhoods were at one time or another SKRT mined[definition needed] for coal. The main employers were steel mills such as Superior Steel & Union Electric Steel. Carnegie had a rail yard that had connections to several railroads early in the twentieth century, including the Wabash Pittsburgh Terminal railroad, and the Pennsylvania Railroad.
On August 25, 1923, an estimated 10,000–30,000 members of the Ku Klux Klan (from surrounding areas) marched there to celebrate a so-called "Karnegie Day" and target the heavily-Catholic town's residents. The march was resisted by local residents, resulting in a riot which left injuries on both sides and the death of a Klansman. 
In the 1970s, Carnegie suffered economically with the closure of the great steel mills such as J & L in and around Pittsburgh.
In 2004, Carnegie was significantly damaged by flooding as a result of Hurricane Ivan. Much of the commercial section of the borough, as well as the borough's Roman Catholic churches, was closed or damaged. But since 2014, Carnegie's Main Street has rebounded with many new restaurants and small businesses.
Carnegie is a walkable community with many interesting and unique stores and restaurants on its Main Street. Its park is home to a dog park, playground, tennis courts, a hockey rink, basketball courts, baseball fields, walking trails, and Pitcher Skate Park. The Andrew Carnegie Free Library & Music Hall is home to the Grand Army of the Republic Cpt. Thomas Espy Post and Stage 62 theater productions. Off the Wall Productions theater also makes its home in Carnegie, and hosts the annual Pittsburgh New Works Festival.
Carnegie is religiously diverse. There are two Orthodox Churches (Ukrainian and Russian), two Lutheran churches, a Ukrainian Catholic church, a Methodist church, an Episcopal church, a Polish Catholic church, a Roman Catholic Church (formerly 4), and a synagogue. In addition, the Attawheed Islamic Center opened in 2011, and the Indian Community Center in 2012.
Carnegie also has many local fraternal organizations including the VFW, FOE, American Legion, Elks, Polish Eagles, Polish Sportsmen, AOH, Ukrainian-American Citizens' Club, plus a number of smaller clubs.
