The Strait of Hormuz is a strait between the Persian Gulf and the Gulf of Oman. It provides the only sea passage from the Persian Gulf to the open ocean and is one of the world's most strategically important choke points. On the north coast lies Iran, and on the south coast lies the Musandam Peninsula, shared by the United Arab Emirates and the Musandam Governorate, an exclave of Oman. The Strait is about 104 miles (90 nmi; 167 km) long, with a width varying from about 60 mi (52 nmi; 97 km) to 24 mi (21 nmi; 39 km).
As of 2023, 20% of the world's liquefied natural gas and 25% of seaborne oil trade passes through the Strait, making it a highly important location for trade. It has been so for centuries; its vast hinterlands were rich in luxury trade goods with no easy access to lucrative trading ports. Babur's memoirs recount how almonds had to be carried from the distant Ferghana region to Hormuz, to reach markets.
As of June 2025, the Strait has never been closed during Middle East conflicts, unlike the Straits of Tiran.
