Overview
The term "Arabian Gulf" is commonly used to refer to the shallow sea that lies between the Arabian Peninsula and the southern coast of Iran. Internationally the waterway is most often called the Persian Gulf; the choice of name reflects political and historical differences. The seaway connects to the Arabian Sea through the Strait of Hormuz and is a distinct arm of the Indian Ocean.
Geography and environment
This gulf is a semi-enclosed basin with extensive coastlines, tidal flats and islands. Its waters are relatively shallow compared with open oceans and are subject to high evaporation rates, warm temperatures and variable salinity. Key physical features include the Strait of Hormuz at the east and numerous archipelagos and coastal inlets.
- Bordering countries: Iran, Iraq, Kuwait, Saudi Arabia, Bahrain, Qatar, United Arab Emirates and the Musandam exclave of Oman.
- Notable islands: Bahrain, Qeshm, Hormuz, Abu Musa and the Tunbs (Greater and Lesser).
History and naming
Ports along this gulf have been linked to trade and maritime activity since antiquity. Ancient and medieval writers used various names for the waters and adjacent lands. In modern times, the name "Persian Gulf" has deep historical usage in many languages and maps. From the mid-20th century onward, some Arab states and institutions adopted "Arabian Gulf" for political and national identity reasons, making the name a subject of diplomatic sensitivity.
Economic and strategic importance
The gulf region is one of the world’s most important hydrocarbon-producing areas; offshore fields and onshore terminals support global energy markets. Major shipping lanes cross the gulf and the Strait of Hormuz, creating strategic choke points for maritime traffic. The coastal economies rely on ports, fishing, desalination and petrochemical industries, while environmental pressures include pollution risks and habitat loss.
Uses of the term and notable facts
Beyond geography, "Arabian Gulf" appears in the names of sports competitions, universities and companies in the region. Its use can signal political alignment or cultural affiliation. Because naming remains contested, many international organizations and atlases note both terms or follow established conventions to avoid diplomatic disputes.
