The Uyunid dynasty (Arabic: العيونيون, romanized: al-ʿUyūnīyūn) were an Arab dynasty that ruled Eastern Arabia for 163 years, from the 11th to the 13th centuries. Their sect is disputed; some sources mention they were Shia, others Sunni. They were the remnants of Banu Abdul Qays tribe and seized the country from the Qarmatians with the military assistance of Great Seljuq Empire in the year 1077–1078 CE. It then fell to the Usfurids of Banu Uqayl in 651 AH (1253 CE). The famous poet Ali bin al Mugrab Al Uyuni is a descendant of the Uyunids.
