The Musandam Governorate (Arabic:محافظة مسندم‎) is a governorate of Oman. It is located on the Musandam peninsula, which juts into the Strait of Hormuz, the narrow entry into the Persian Gulf, from the Arabian Peninsula. The Governorate is an exclave of Oman, separated from the rest of the country by the United Arab Emirates. Its location gives Oman partial control, shared with Iran, of the strategic strait. In the northern section of Musandam, around Kumzar, the language is Kumzari, which is a southwestern Iranian language closely related to Larestani and Luri. The Musandam Peninsula has an area of 1,800 square kilometers (695 sq mi) and a population of 31,425 people.
