Arnekhamani was a Nubian king of the Kushite Kingdom in the third century BC.

The king is mainly known from his building activity at the Musawwarat es-Sufra temple complex.

The main temple complex at this place was built by Arnekhamani, but was never finished.

The Egyptian king Ptolemy IV Philopator (221–204 BC) is also called in his Egyptian name beloved of Isis and it seems possible that Arnekhamani's name was influenced by the name of the Egyptian king, providing a chronological fixpoint for the rule of Arnekhamani.

The son is called Arky and bears the title Priest of Isis, of Ipeber-ankh (Musawwarat es-Sufra).
