Artavasdes I - Basileus of Kingdom of Armenia from 159 BC to 123 BC
Artavasdes I reigned as King of Armenia from 159 BC to 123 BC and was the son of Artaxias I and Satenik.

Artavasdes repelled several attempts by Parthians to invade Armenia but was eventually defeated by Mithridates, who annexed parts of Eastern Armenia and took his son, Tigranes the Great as hostage.

Artavasdes I can be identified with the Armenian king who, according to the medieval Georgian annals, interfered in Iberia at the request of local nobility and installed his son, Artaxias, on the throne of Iberia, thereby inaugurating the Iberian Artaxiad dynasty.
