Aakheperre Setepenre Osorkon the Elder was the fifth king of the twenty-first dynasty of Ancient Egypt and was the first Pharaoh of Libyan origin. He is also sometimes known as Osochor, following Manetho's Aegyptiaca.

Osorkon the Elder was the son of Shoshenq A, the Great Chief of the Ma by the latter's wife Mehtenweshkhet who is given the prestigious title of 'King's Mother' in a document. Osochor was the brother of Nimlot A, the Great Chief of the Ma, and Tentshepeh A the daughter of the Great Chief of the Ma and, thus, an uncle of Shoshenq I, founder of the Twenty-second Dynasty. His existence was doubted by most scholars until Eric Young established in 1963 that the induction of a temple priest named Nespaneferhor in Year 2 I Shemu day 20 under a certain king named Aakheperre Setepenre—in fragment 3B, line 1-3 of the Karnak Priest Annals —occurred one generation prior to the induction of Hori, Nespaneferhor's son, in Year 17 of Siamun, which is also recorded in the same annals. Young argued that this king Aakheperre Setepenre was the unknown Osochor. This hypothesis was not fully accepted by all Egyptologists at that time, however.

Then, in a 1976-77 paper, Jean Yoyotte noted that a Libyan king named Osorkon was the son of Shoshenq A by the Lady Mehtenweshkhet A, with Mehtenweshkhet being explicitly titled the "King's Mother" in a certain genealogical document. Since none of the other kings named Osorkon had a mother named Mehtenweshkhet, it was conclusively established that Aakheperre Setepenre was indeed Manetho's Osochor, whose mother was Mehtenweshkhet. The Lady Mehtenweshkhet A was also the mother of Nimlot A, Great Chief of the Meshwesh and, thus, Shoshenq I's grandmother.

In 1999 Chris Bennett made a case for a Queen Karimala known from an inscription in the temple of Semna being his daughter. She is called both 'King's Daughter" and "King's Wife". Her name suggests she may have been Libyan. Given the date of the inscription (a year 14), she might have been the queen of either king Siamun or king Psusennes II. Bennett prefers a marriage to Siamun, because in that case she could have taken over the position of the Viceroy of Kush, Neskhons, as a religious figurehead in Nubia after the death of the latter in year 5 of king Siamun.
