Pinedjem I was the high priest of Amun at Thebes in Ancient Egypt 1070 BC to 1032 and de facto ruler of the south of the country.

Inheriting a powerbase at Thebes from his father Piankh Pinedjem strengthened his grip on large swathes of Egyptian territory at the expense of the feeble Twenty-first Dynasty based at Tanis. He married Henuttawy, a daughter of Ramesses XI to cement his relations with the other powerful families of the period. His son became Psusennes I , Pharaoh at Tanis, thus erasing at a stroke the gap between the two families. In practice the 21st dynasty and their high priests were never very far apart.

Pinedjem was succeeded in his priestly role by his two other sons Masaherta and Menkheperre. His daughter Maatkare held the position of divine adoratrice of Amun.

Pinedjem's mummy was found in the cache at Deir el-Bahri.
