阿尔塔瓦兹德二世（亚美尼亚语：Արտավազդ Երկրորդ，？—前34年）大亚美尼亚国王（前53年—前34年）。提格兰大帝之子。他是一个政治上的失败者，又是一位诗人和艺术家。

阿尔塔瓦兹德二世力图重振亚美尼亚的国势，尤其是要摆脱罗马的控制，为此不惜与帕提亚人联合。前53年，由克拉苏率领的罗马军队在进攻帕提亚的战争中被帕提亚国王奥罗德二世击溃，克拉苏本人阵亡。这次惨痛的失败使正处于非常时期的罗马无力东顾，大亚美尼亚的独立因此得以保全。阿尔塔瓦兹德二世趁机收复了在提格兰大帝统治末期被罗马强行割走的小亚细亚。为巩固与帕提亚人的联盟，阿尔塔瓦兹德二世让妹妹与奥罗德二世之子和继承人帕科鲁斯结婚。

Artavasdes II (Ancient Greek: ΒΑΣΙΛΕΟΣ ΑΡΤΑΥΑΖΔΟΥ Basileos Artavazdou, Armenian:Արտավազդ Երկրորդ Artavazd Ikrord) was a King of the Kingdom of Armenia from 54 BC until 34 BC and a member of the Artaxiad Dynasty. He succeeded his father, Tigranes the Great, also known as Tigranes II. Artavasdes II was an ally of Rome, but when Orodes II of Parthia invaded Armenia following his victory over the Roman general Marcus Licinius Crassus at the Battle of Carrhae in 53 BC, he was forced to join the Parthians. He gave his sister in marriage to Orodes' son and heir Pacorus.
