The South Saqqara Stone is the lid of the sarcophagus of the ancient Egyptian queen Ankhesenpepi I, which was inscribed with a list for the reigns of the pharaohs of the 6th Dynasty from Teti, Userkare, Pepi I, Merenre to the early years of Pepi II under whom the document was likely created.

It is essentially an annal document which records events in each year of a king's reign; unfortunately, it was reused in antiquity for Ankhesenpepi I's burial and many of its invaluable inscriptions have been erased.

The South Saqqara Stone was discovered in 1932 or 1933 by Gustave Jéquier in the westernmost of five storerooms south of the pyramid of Queen Iput II, within the pyramid complex of Pepi II (during whose reign it was created) at Saqqara.

The importance of the South Saqqara Stone stems from its inscription: a list of a number of pharaohs, along with details of annual or biannual cattle counts which confirm details in other sources (such as the Turin King List), and allow archaeologists to estimate the length of their reigns.

The Stone is considered one of the earliest historical documents in existence, as it is not merely a list of dynastic ancestors for the ruling pharaoh, but includes the names of all preceding pharaohs known to the artefact's creators, including shadowy rulers such as Userkare.
