Ahmad ibn Ismail (Persian: احمد سامانی; died 24 January 914)[1] was amir of the Samanids (907–914).

Some time afterwards, he was granted the rights to Sistan, the heart of the Saffarid realm, by Caliph al-Muqtadir.

At the same time, Ahmad's Turkic general Simjur al-Dawati received the surrender of Zarang from al-Mu'addal.

The conquest of the Saffarids complete (911), Ahmad appointed his cousin Abu Salih Mansur as governor of Sistan in the following year.

Amr ibn Ya'qub, a Saffarid, was installed, first as a puppet for the leader of the rebellion, then as amir in his own right.
