{{Short description|Emir of Crete from c. 910 to c. 915}}
'''Yusuf ibn Umar ibn Shu'ayb''' ({{langx|ar|يوسف بن عمر بن شعيب}}) was the fifth [[Emir of Crete]], reigning from {{circa|910–915}}.
The surviving records on the internal history and rulers of the [[Emirate of Crete]] are very fragmentary. He is tentatively identified as a son of the third emir, [[Umar II ibn Shu'ayb|Abu Abdallah Umar (II)]], and the grandson of the conqueror of [[Crete]] and founder of the emirate, [[Abu Hafs Umar al-Iqritishi|Abu Hafs Umar]]. He is believed to have reigned from {{circa|910}} to {{circa|915}}, succeeding his uncle, [[Muhammad ibn Shu'ayb al-Zarkun|Muhammad]].{{sfn|Miles|1964|pp=11–14}}{{sfn|Canard|1971|p=1085}}{{sfn|PmbZ|loc=Yūsuf b. ‘Umar II. (#28473)}}
In 909/10, the unnamed author of the [[hagiography]] of [[Theoktiste of Lesbos]] was sent to Crete as an envoy to ascertain whether the local Arabs would make common cause with the [[Abbasid]] fleets operating from Syria.{{sfn|Canard|1971|p=1084}} In 911, the Byzantines launched a large-scale expedition, with over 100 ships and 43,000 men, to recapture the island, but were driven off. On its return journey, the Byzantine fleet was destroyed in an ambush off [[Chios]] by the Syrian fleet.{{sfn|Canard|1971|p=1084}}{{sfn|Treadgold|1997|pp=469–470}} Yusuf is presumably the unnamed Emir of Crete addressed in a letter by Patriarch [[Nicholas I Mystikos]] in 913/14.{{sfn|PmbZ|loc=Yūsuf b. ‘Umar II. (#28473)}}
He was succeeded by his son, [[Ali ibn Yusuf ibn Umar|Ali]].{{sfn|Miles|1964|pp=11–14}}{{sfn|Canard|1971|p=1085}}{{sfn|PmbZ|loc=Yūsuf b. ‘Umar II. (#28473)}}
