Yazid ibn Umar ibn Hubayra al-Fazari (Arabic: يَزِيد بن عُمَر بن هُبَيْرَة الْفَزارِيّ, romanized: Yazīd ibn ʿUmar ibn Hubayra al-Fazārī; died 750) was the last Umayyad governor of Iraq. A son of former governor Umar ibn Hubayra, he became one of the most important partisans of Caliph Marwan II in the Third Fitna, but failed to stem the onslaught of the Abbasid Revolution. Defeated, he was captured and executed by the Abbasids.
