Shahriyar I (Persian: شهریار) was the sixth ruler of the Bavand dynasty from 817 to 825.
After Shahriyar's coronation, the Abbasid caliph al-Ma'mun, sent him robes of honour, and requested his and the Qarinvand ruler Qarin ibn Vindadhhurmuzd's aid in the Arab–Byzantine wars.
Shahriyar declined the request, while Qarin accepted, and became successful in his campaign against the Byzantines.
Shahriyar, jealous of Qarin's fame, began annexing some of the latter's territory.
