Abū ʿAbdallāh ʿUmar II ibn Shuʿayb, also Babdel (Greek: Βαβδέλ) in the Byzantine sources, was the third Emir of Crete, ruling ca. 880 – ca. 895. The surviving records on the internal history and rulers of the Emirate of Crete are very fragmentary. Following the studies of George C. Miles with the aid of numismatic evidence, he is tentatively identified as a son of the second emir, Shu'ayb, and the grandson of the conqueror of Crete and founder of the Emirate of Crete, Abu Hafs Umar. His reign is placed from ca. 880 to ca. 895. According to the Byzantine chronicler Genesios, sometime in the reign of the Byzantine emperor Leo VI the Wise (r. 886–912) he suffered a shipwreck off the coast of the Peloponnese, and was taken captive by the local governor, Constantine Tessarakontapechys.
