Yazid bin Abd al-Malik or Yazid II (687 – 26 January 724) (Arabic: يزيد بن عبد الملك‎‎) was an Umayyad Caliph who ruled from 720 until his death in 724.

Yazid married a daughter of Muhammad ibn Yusuf al-Thaqafi, the brother of the longtime governor of Iraq, al-Hajjaj ibn Yusuf al-Thaqafi. Together they had a son, the future al-Walid II.

According to the medieval Persian historian Muhammad ibn Jarir al-Tabari, Yazid came to power on the death of Umar II on February 10, 720. His forces engaged in battle the Kharijites with whom Umar had been negotiating. After initial setbacks, Yazid's troops prevailed and the Kharijite leader Shawdhab was killed. Yazid ibn al-Muhallab had escaped confinement on the death of Umar. He made his way to Iraq. There he was much supported. He refused to acknowledge Yazid II as caliph and led a very serious uprising. Initially successful, he was defeated and killed by the forces of Maslamah ibn Abd al-Malik.

Numerous civil wars began to break out in different parts of the empire such as in the Al Andalus (the Iberian Peninsula), North Africa and in the east. In A.H. 102 (720-721) in Ifriqiyah, the harsh governor Yazid ibn Muslim was overthrown and Muhammad ibn Yazid, the former governor, restored to power. The caliph accepted this and confirmed Muhammad ibn Yazid as governor of Ifriqiyah.

Al-Jarrah ibn Abdallah, Yazid's governor in Armenia and Adharbayjan, pushed into the Caucasus, taking Balanjar in A.H. 104 (722-723). That same year Yazid's governor in Medina, Abd al-Rahman ibn al-Dahhak, incurred the caliph's displeasure because the governor was exerting undue pressure trying to force a woman to marry him. She appealed to Yazid who replaced Abd al-Rahman with Abd al-Walid ibn Abdallah.
