Shahrag (also spelled Shahrak) was an Iranian aristocrat, who served as the governor of Pars during the Arab invasion of Iran.
He is first mentioned in 644, when he defeated the Arab military leader al-Ala'a Al-Hadrami near Estakhr. Some time later, Uthman ibn Abi al-'As established a military base at Tawwaj, and shortly after defeated and killed Shahrag near Rew-shahr (however other sources states that it was Shahrak's brother who killed him).
