Uqair (Arabic:عقير) is an ancient fort of Islamic origin, located in the Eastern Province, Saudi Arabia. It is alternatively spelled Al-'Uqair, Uqayr, and Ogair, all Latin transliterations of the same Arabic word. It has been linked by some to the ancient city of Gerrha mentioned in Greek and Roman sources. The site was also the location of the conference at which the Uqair Protocol of 1922 was issued, which helped to establish the borders of modern Saudi Arabia.
