Abu `Abdallah Muhammad XII (Arabic: أبو عبد الله محمد الثاني عشر‎ Abū ‘Abd Allāh Muḥammad al-thānī ‘ashar) (c. 1460 – c. 1533), known as Boabdil (a Spanish rendering of the name Abu Abdullah), was the twenty-second and last Nasrid ruler of Granada in Iberia. He was also called el chico, the little, or el zogoybi, the unfortunate. Son of Abu l-Hasan Ali, sultan of the Emirate of Granada, he was proclaimed sultan in 1482 in place of his father, who was driven from the land.

Muhammad XII soon after sought to gain prestige by invading Castile. He was taken prisoner at Lucena in 1484. Between 1484 and 1487, he was held prisoner. Power returned to his father and then in 1485 to his uncle Muhammed XIII, also known as Abdullah ez Zagal.

He only obtained his freedom and support to recover his throne in 1487 by consenting to hold Granada as a tributary kingdom under Ferdinand and Isabella, king and queen of Castile and Aragon, and not to intervene to prevent the conquest of Málaga.

1487 saw the fall of Baeza, Málaga and Almería. 1489 saw the fall of Almuñécar and Salobreña. By the beginning of 1491, Granada was the only Muslim-governed city in Spain.
