Allegheny Cemetery is one of the largest and oldest burial grounds in Pittsburgh, Pennsylvania, USA.
It is a nonsectarian, wooded hillside park located at 4734 Butler Street in the Lawrenceville neighborhood and bounded by Bloomfield, Garfield, and Stanton Heights. It is sited on the north-facing slope of hills above the Allegheny River.
Incorporated in 1844, the Allegheny Cemetery is the sixth oldest rural cemetery in America and has expanded over the years to now encompass 300 acres (1.2 km²).
Allegheny Cemetery memorializes more than 100,000. Some of the oldest graves are of soldiers who fought in the French and Indian War, which were moved here from their original burial site at Pittsburgh's Trinity Cathedral downtown. Many notables from the city of Pittsburgh are buried here. The cemetery was amongst those profiled in the PBS documentary A Cemetery Special.
