Persian Gulf, Arabic Baḥr Fāris, Persian Khalīj-e Fārs, also called Arabian Gulf, shallow marginal sea of the Indian Ocean that lies between the Arabian Peninsula and southwestern Iran. The sea has an area of about 93,000 square miles (241,000 square km). Its length is some 615 miles (990 km), and its width varies from a maximum of about 210 miles (340 km) to a minimum of 35 miles (55 km) in the Strait of Hormuz. It is bordered on the north, northeast, and east by Iran; on the southeast and south by part of Oman and by the United Arab Emirates; on the southwest and west by Qatar, Bahrain, and Saudi Arabia; and on the northwest by Kuwait and Iraq. The term Persian Gulf (or Arabian Gulf, the name used by Arabs) sometimes is employed to refer not only to the Persian Gulf proper but also to its outlets, the Strait of Hormuz and the Gulf of Oman, which open into the Arabian Sea. This discussion, however, focuses primarily on the Persian Gulf proper.
