Pharasmanes I (Georgian: ფარსმან I) (died 58) was a king of Iberia. He plays a prominent role in the historian Tacitus’ account of policy and campaigns in the eastern Roman Empire under Tiberius, Caligula, Claudius and Nero. According to Cyril Toumanoff, Pharasmanes was a member of the third Pharnavazid dynasty and reigned from 1 to 58. Pharasmanes is mentioned on the Stele of Vespasian. During his reign, Iberia was transformed into the Transcaucasian empire, that would dominate the kingdoms of Armenia and Albania.
