Ahmad (d. 864/865) was a Samanid ruler of Ferghana (819-864/5) and Samarkand (851/2-864/5). He was a son of Asad.

In 819 Ahmad was granted authority over the city of Ferghana by Caliph Al-Ma'mun's governor of Khorasan, Ghassan ibn 'Abbad, as a reward for his support against the rebel Rafi' ibn Laith. Following the death of his brother Nuh, who ruled in Samarkand, Ahmad and another brother Yahya were given rule over the city by Abdallah, the governor of Khurasan. Yahya's power was subsequently significantly curtailed by Ahmad, and he may have ruled as simply a figurehead until his death in 855. Yahya's line was then superseded by Ahmad's. By the time of Ahmad's death in 864 or 865, he was the ruler of most of Transoxiana, bar Bukhara and Khwarazm. Samarkand went to one son, Nasr I, while Shash went to another son, Ya'qub.
