Uqair (Arabic: عقير), alternatively spelled as al-'Uqair, Uqayr, and Ogair, is an ancient seaport city in the Al-Ahsa Governorate of the Eastern Province of Saudi Arabia. It is the first seaport in the Persian Gulf and 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.
