Psusennes III (also known as Pasebakhaennuit III) was the High Priest of Amun (1080 - 945 BC) at the end of the Twenty-first dynasty of Egypt. Little is known of this individual; he is almost certainly the same person as king Psusennes II. His name appears on a document found at DB320 which describes him as a son of the High Priest Pinedjem II.
