Pacorus II of Parthia ruled the Parthian Empire from about 78 to 105. According to Dio Cassius he sold the kingdom of Osroene to Abgar VII , and according to Ammianus Marcellinus he enlarged the Parthian Ctesiphon and built its walls.

On his numerous coins he always calls himself "Arsaces Pacorus". This mention of his proper name, together with the royal name Arsaces, shows that his kingdom was disputed by rivals. Three of them we know from coins Vologases II, c. 78–80, Artabanus III, c. 80–90 and Vologases III, from about 105.

Pacorus died about 105; he was succeeded by his brother Osroes I.
