The Uyunid Emirate (Arabic: الدولة العيونية) was an emirate centered in al-Hasa that ruled Eastern Arabia and Najd at its greatest extent. The emirate was ruled by the Uyunid dynasty, an Arab dynasty from the tribe of Banu Abd al-Qays. The emirate was established in 1076 after the Uyunids took over control from the Qarmatians and was ended in 1253 when it was overthrown by the Usfurids.
