Pi-Sekhemkheperre or Per-Sekhemkheperre, was an ancient Egyptian stronghold. Its name means "The estate of Sekhemkheperre", a reference to Sekhemkheperre Osorkon I, the pharaoh of the early 22nd Dynasty who founded the fortress during his reign (about 922 to 887 BCE). It has been suggested that its erection may be a symptom of the state of general insecurity in the country during the period.Pi-Sekhemkheperre is at yet undiscovered but it is believed that it lies somewhere at the entrance of the Faiyum, just north to Herakleopolis Magna in Middle Egypt.
