Yazid ibn Asid ibn Zafir al-Sulami or Yazid ibn Usayd ibn Zafir al-Sulami in Arabic يزيد بن أسيد السلمي was an Arab general and governor in the service of the early Abbasid Caliphate. He was active mostly in the Caliphate's northwestern frontier region, serving as governor of Arminiya and the Jazira and fighting against the Byzantine Empire and the Khazars.

Yazid was a member of the Banu Sulaym tribe, which had participated in the Muslim conquest of Armenia and been settled by the caliphs in the western Armenian borderlands with the Byzantine Empire. Yazid's father, Asid (or Usayd) ibn Zafir al-Sulami, had been a general in the service of the Umayyads, and served under the last Umayyad caliph, Marwan ibn Muhammad, and his father, Muhammad ibn Marwan, in their campaigns in the region.Al-Baladhuri further reports that his mother was a Christian, the daughter of the "Patrician of Siwnik", who had been taken captive during Muhammad ibn Marwan's campaigns.

Despite his close ties to the Umayyads, Yazid became a close and trusted advisor to the Abbasid prince Abu Ja'far, the future Caliph al-Mansur (r. 754–775), during the early years of the Abbasid regime. Yazid hence served thrice as governor of Arminiya (a huge province encompassing most of Arab-controlled Transcaucasia), in 752–754, 759–770, and 775–780. Under al-Mansur, he also served concurrently as governor of Mosul (and apparently of the entire Jazira).
