Ahmad ibn Asad (d. 864/865) was a Samanid Amir of Ferghana (819-864/5) and Samarkand (851/2-864/5).
Yahya's power was subsequently significantly curtailed by Ahmad, and he may have ruled as simply a figurehead until his death in 855.
By the time of Ahmad's death in 864 or 865, he was the ruler of most of Transoxiana, Bukhara and Khwarazm.
