Hedjkheperre Setepenre Shoshenq I —also known as Shashank or Sheshonk or Sheshonq I—was a pharaoh of ancient Egypt and the founder of the Twenty-second Dynasty of Egypt. Of Meshwesh ancestry, Shoshenq I was the son of Nimlot A, Great Chief of the Ma, and his wife Tentshepeh A, a daughter of a Great Chief of the Ma herself; Shoshenq was thus the nephew of Osorkon the Elder, a Meshwesh king of the 21st Dynasty. He is generally presumed to be the Shishak mentioned in the Hebrew Bible, and his exploits are carved on the Bubastite Portal at Karnak.

The Bubastite Portal gate is located in Karnak, within the Precinct of Amun-Re temple complex, between the temple of Ramesses III and the second pylon. It records the conquests and military campaigns c. 925 BC of Shoshenq I, of the Twenty-second Dynasty. Shoshenq has been identified with the biblical Shishaq, such that the relief is also known as the Shishak Inscription or Shishaq Relief.
