Abu Ahmad Wali 'l-Dawla Khalaf ibn Ahmad (November 937 – March 1009) was the Saffarid amir of Sistan from 963 until 1002. Although he was renowned in the eastern Islamic world as a scholar, his reign was characterized by violence and instability, and Saffarid rule over Sistan came to an end with his deposition.
