Harthamah Shar Bamiyan (Arabic: هرثمة شارباميان) was a ninth century personage and provincial governor for the Abbasid Caliphate.
Following the conversion of the princes of Bamiyan to Islam in the late eighth century, members of the dynasty had entered into the service of the Abbasids and held influential positions at the caliphal court in Iraq.
[2] During the caliphate of al-Wathiq (r. 842–847) Shar Bamiyan was appointed as Itakh's resident governor of the Yemen, in response to a Yemeni appeal for reinforcements against the rebellion of the Yu'firids.
After arriving in the Yemen in early 844, he advanced with his army and placed the Yu'firids under siege at Jabal Dhukhar, but his forces failed to breach the rebel fortress.
Seeing that he was making no progress against the insurgents, Shar Bamiyan eventually decided to withdraw and retired to Sana'a, leaving the Yu'firid position intact.
