Orodes II of Parthia (Persian: ارد دوم‎‎), (also called Hyrodes Anaridius) was the king of the Parthian Empire from 57 BC to 37 BC. Orodes was a son of Phraates III, whom he murdered in 57 BC, assisted by his brother Mithridates. He married a Greek Princess from the Kingdom of Commagene, called Laodice who was a daughter of King Antiochus I Theos of Commagene and Queen Isias Philostorgos of Commagene.

Orodes' brother Mithridates was made king of Media; but, soon afterwards, Mithridates was disposed by Orodes and forced to flee to Syria. Mithridates then returned to invade the Parthia, restoring his reign as king briefly in 55 BC. However, king Mithridates was besieged by Orodes' general, Surena, in Seleucia on the Tigris: after a prolonged resistance, Mithridates was captured and slain.

Meanwhile, the Roman general and triumvir Marcus Licinius Crassus had made an attempt to extend his share of Roman territory by eastward conquest, and in the event had been decisively defeated and killed in 53 BC, in the Battle of Carrhae, along with his son and with the loss of most of his army, by Orodes' general Surena. Orodes himself had invaded Armenia and forced King Artavasdes, the son of Tigranes the Great to submit and abandon his alliance with the Romans. The victory at Carrhae secured for the Parthians the countries east of the Euphrates. Then, the next year they invaded Syria, but with little success, for Surena, whose achievements had made him too dangerous, was killed by Orodes.
