Neferkare Amenemnisu' was a pharaoh of the 21st Dynasty of ancient Egypt.
Amenemnisu's existence was only confirmed in 1940 when the tomb of his successor Psusennes I was discovered by Pierre Montet.
Previously, his existence had been doubted as no objects naming him had been discovered. However, the memory of his short rule as
the second pharaoh of the 21st Dynasty was preserved in Manetho's Epitome as a king Nephercheres who is assigned a short reign of 4
years. Amenemnisu's name means "Amun is King" in Egyptian.
While his reign is generally obscure, the serving High Priest of Amun at Thebes, Menkheperre, is known to have pardoned several
leaders of a rebellion against this Priests authority during Amenemnisu's reign. These rebels had previously been exiled to the
Western Oasis of Egypt in Year 25 of Smendes. A gold bow cap inscribed with both Amenemnisu's royal name, Neferkare, and that of his
successor Psusennes I was discovered in the tomb of Psusennes I.
