Abu ʿAmr ʿAbbad II al-Muʿtadid (Arabic: المعتضد بالله أبو عمرو عبَّاد; died 28 February 1069), a member of the Abbadid dynasty, was the second independent emir of Seville (reigned 1042–1069) in Al-Andalus.

He initially had amicable relations with his neighbour Ferdinand I, Count of Castile and King of León, and tolerated the Christian faith in his own lands.

Among other acts of friendship, he authorized the transfer of Saint Isidore's relics from Seville to the Basilica of San Isidoro in León.

Al-Muʿtadid expanded his territory by conquering numerous Islamic taifas (independent principalities),[1] including those of Mértola (1044–45), Huelva (1051), Algeciras (1055), Ronda (1065) and Arcos (1069).

In 1063, when Ferdinand I appeared with an army on the outskirts of Seville, Al-Muʿtadid was forced to acknowledge his suzerainty and to pay him tribute.
