The Hajar Mountains are one of the highest mountain ranges in the Arabian Peninsula, shared between northern Oman and eastern United Arab Emirates. Also known as "Oman Mountains", they separate the low coastal plain of Oman from the high desert plateau, and lie 50–100 km (31–62 mi) inland from the Gulf of Oman.

It shares land borders with Saudi Arabia, the United Arab Emirates, and Yemen, while sharing maritime borders with Iran and Pakistan. The capital and largest city is Muscat. Oman has a population of nearly 4.7 million and is the 124th most-populous country. The coast faces the Arabian Sea on the southeast, and the Gulf of Oman on the northeast. The Madha and Musandam exclaves are surrounded by United Arab Emirates on their land borders, with the Strait of Hormuz and the Gulf of Oman forming Musandam's coastal boundaries.
