Neferkare Amenemnisu was an ancient Egyptian pharaoh, the second king of the 21st Dynasty.

Amenemnisu's existence was only confirmed in 1940 when the Tanite tomb of his successor Psusennes I was discovered by Pierre Montet: a gold bow cap inscribed with both Amenemnisu's royal name, Neferkare, and that of his successor Psusennes I was found within the tomb.

[2] While his reign is generally obscure, the then High Priest of Amun at Thebes, Menkheperre, is known to have pardoned several leaders of a rebellion against the High Priest's authority during Amenemnisu's reign.

[1] These rebels had previously been exiled to the Western Oasis of Egypt in Year 25 of Smendes.

These events are reported on the so-called Banishment Stela (Louvre C. 256), likely made during the brief reign of Amenemnisu.
