Alter Friedhof (Old Cemetery) is a historically significant cemetery in Bonn, Germany, 1.2 hectares (3 acres) in area, located near the center of the modern city.^[1]

The cemetery was established in 1715 as a cemetery for soldiers and strangers, outside the city walls of the time. It remained in regular use until the new North cemetery opened in 1884, after which burials gradually ceased. It is an area of greenery in the middle of the modern city.
