Pherendates (Old Persian: *Farnadātaʰ;^[1] Ancient Greek: Φερενδάτης Pherendā́tēs) was an Achaemenid satrap of ancient Egypt in the early 5th century BCE, at the time of the Achaemenid 27th Dynasty of Egypt.

A son of Megabazus, and an army commander under king Darius I,^[2] Pherendates is mainly attested from three letters written in Egyptian Demotic. He replaced the satrap Aryandes who was deposed by Darius around 496 BCE;^[1] although the exact accession date of Pherendates is unknown. Pherendates was definitely the satrap in 492 BCE.^[3]

In the aforementioned letters, certain priests of the local temple of Khnum at Elephantine asked Pherendates to take care of some of their business in their place, a rather standard request to the pharaoh (or his representative, such as in this case) in any period of ancient Egyptian history.^[1]

In 486–485 BCE a revolt occurred in Egypt, which was quelled in 484 BCE by a new satrap, Achaemenes. It is possible that Pherendates lost his life during the turmoil.^[1]
