The Gulf of Oman or Sea of Oman (Arabic:Ḫalīdj ʾUmān; alternatively known as , Ḫalīdj Makrān; in Persian: Daryā-ye Ommān, or Daryā-ye Makrān, or Daryā-ye Pārs; in Urdu: Khaleej Oman) is a strait (and not an actual gulf) that connects the Arabian Sea with the Strait of Hormuz, which then runs to the Persian Gulf. It is generally included as a branch of the Persian Gulf, not as an arm of the Arabian Sea. The gulf borders Pakistan and Iran on the north, Oman on the south, and the United Arab Emirates on the west.
The International Hydrographic Organization defines the limits of the Gulf of Oman as follows:
- On the Northwest. A line joining Ràs Limah (25°57’N) on the coast of Arabia and Ràs al Kuh (25°48’N) on the coast of Iran (Persia)
- On the Southeast. The Northern limit of the Arabian Sea [A line joining Ràs al Hadd, East point of Arabia (22°32’N) and Ràs Jiyùni (61°43’E) on the coast of Pakistan].
