Samura ibn Jundab al-Fazārī (Arabic: سمرة بن جندب, his father Jundab's name is also commonly transliterated as Jundub; died 677–679) was a companion of the Islamic prophet Muhammad who fought at the Battle of Uhud in 627 and later participated in the Muslim conquest of Iran in the 630s–640s. In 670–673 he served as the lieutenant governor of Basra under Ziyad ibn Abihi, the supreme governor of Iraq and the eastern Umayyad Caliphate. During his deputy rule over Basra, he is held by the Islamic traditional sources to have ordered wide-scale executions of Kharijites in his jurisdiction. He remained governor of Basra under the Umayyad caliph Mu'awiya I (r. 661–680) for six to eighteen months after Ziyad's death in August/September 673 until the Caliph replaced him.
