Yusuf ibn 'Abd al-Rahman al-Fihri (Arabic: يوسف بن عبد الرحمن الفهري) was Umayyad governor of Narbonne in Septimania and then from 747 to 756 governor of al-Andalus, ruling independently following the collapse of the Umayyad Caliphate in 750. He was a descendant of 'Uqbah, the founder of al-Qayrāwan.
Between 716 and 756, al-Andalus was ruled by governors sent from Damascus or appointed on the recommendation of the Umayyad regional governors of Ifriqiya to which it belonged administratively . Like many of his predecessors Yusuf struggled to control infighting between the majority Berber population and the Arabs and also had to deal with perennial feuding between Syrian and Yemeni Arab tribes comprising his forces.
After becoming ruler, al-Fihri conducted a census, as part of which Bishop Hostegesis prepared a list of tax and jizya payers. The bishop then made annual visits to makes sure the taxes were collected properly.
Al-Fihri led a campaign against the Basques of Pamplona in 755 but was defeated and is said to have horrified tribal sensibilities by raping two of Abd ar-Rahman's slaves, thus contributing to the factional conflicts in al-Andalus at that time.
Yusuf al-Fihri was defeated at the Battle of Musarah just outside Córdoba in March 756 by Abd ar-Rahman I, who, having fled Syria in 755 to escape from the Abbasids, became the first Emir of Córdoba.
