Cleomenes (died 322 BCE), a Greek of Naucratis in Egypt, is appointed by Alexander III of Macedon as nomarch of the Arabian district of Egypt and receiver of the tributes from all the districts of Egypt and the neighboring part of Africa (331 BCE).

Some of the ancient writers say that Alexander made him satrap of Egypt; but this is incorrect, for Arrian expressly states that the other nomarchs were independent of him, except that they had to pay to him the tributes of their districts.

It would, however, appear that he had no difficulty in extending his depredations over all Egypt, and it is possible that he would have taken the title of satrap.

It is told that his rapacity knew no bounds, that he exercised his office solely for his own advantage.
