The ''''Utub''' ( '''') was an alliance of Arab clans originating from the region of Najd in central Arabia. The tribe is thought to have been formed when a group of disparate clans migrated from Najd to the Persian Gulf coast sometime in the late seventeenth century.
The current ruling families of Bahrain (the Al Khalifa) and Kuwait (the Al-Sabah) belong to the 'Utub, though genealogy|genealogically they trace their descent to the 'Anizzah confederation. Other families of the 'Utub include Al Fazil, Al Jalahma, and Al Bin Ali, and are largely based in Bahrain, Kuwait, and Saudi Arabia.
