Uthman ibn Abi al-As al-Thaqafi (Arabic: عثمان بن أبي العاص, romanized: ʿUthmān ibn Abī al-ʿĀṣ; died 671 or 675) was a companion of the Islamic prophet Muhammad from the tribe of Banu Thaqif and the governor of Bahrayn (eastern Arabia) and Oman (southeastern Arabia) in 636–650, during the reigns of caliphs Umar (r. 634–644) and Uthman (r. 644–656). During his governorship he led military campaigns against the Sasanian Persians in Fars. After his dismissal, he settled with his brothers in Basra where he was granted a large estate by the caliph. He transmitted numerous hadiths to the scholar al-Hasan al-Basri and died in the city.
