Circa 550-500 BCE]] Mitrobates (; ); (fl.c. 525 - 520 BC) was an Achaemenid satrap of Daskyleion (Hellespontine Phrygia) under the reigns of Cyrus the Great, who nominated him for the role, and Cambyses. After Cambyses died, and during the struggles for succession that followed, he is said to have been assassinated, together with his son Cranaspes, by the neighbouring satrap of Lydia, Oroetes, who wanted to expand his Anatolian territories. After the assassination, Oroetes added the territory of Hellespontine Phrygia to his own.

These events took place in the troubled times of the interregnum between Cambyses and Darius I, with the usurpation of Gaumata, who Herodotus refers to as "the Magians". The story of early satraps of Asia Minor, including Mitrobates, was related by Herodotus.
