Fazal Haq Mujahid (Pashto: فضل الحق مجاهد; 1954–1997) was an Afghan military and political leader against the Soviet Union.

Because of his efforts, Nangarhar saw an early and balanced administration amid the disagreeable and severe political situations in the country.

Mujahid was born in 1954 to a highly respected family of Akhunzadgan, his father being Noorulhaq from Rodat district of Nangarhar province.

He was considered one of the few military commanders and political figures who were not under the direct influence of neighboring country's intelligence agency.

He visited Sudan few times to meet President Omar al-Bashir on various political issues.
