Eden Cemetery is a historic African-American cemetery located in Collingdale, Delaware County, Pennsylvania, near Philadelphia. The oldest African-American-owned cemetery in the United States, it was established June 20, 1902. When other black cemeteries in Philadelphia were condemned by the city in the early 20th century, including the Olive Graveyard, Lebanon Graveyard, and Stephen Smith Home Burial Ground, the bodies were re-interred at Eden. The cemetery is still in operation. In July 2008, vandals toppled over 200 headstones in the cemetery, including that of Octavius Valentine Catto.
