Piye (whose name once was transliterated as Piankhi) (died 716 BC) was a Kushite king.

Ruler of Nubia from 747 BC, Piye took advantage of the squabbling of Egypt's rulers and invaded the country in 728 BC, conquering Thebes and Memphis, and receiving the submission of the kings of the Nile Delta. Piye adopted the throne name Menkheperre ('the manifestation of Ra abides') but was much more passionate (in common with many kings of Nubia) about the worship of the god Amun.

He founded the Twenty-fifth dynasty of Egypt and was buried in a pyramid at el-Kurru near Gebel Barkal , a site that would come to be occupied by the tombs of several later members of the dynasty.

Piye was succeeded by his brother Shabaka.
