The largest peninsula in the world is the Arabian Peninsula with a total area of about 1,200,000 square miles (3,100,000 square kilometres). The length, bordering the Red Sea, is approximately 1,200 miles (1,900 kilometres) and the maximum breadth, from Yemen to Oman, 1,300 miles.

The largest political division is Saudi Arabia; it is followed, in order of size, by Yemen, Oman, the United Arab Emirates, Kuwait, Qatar, and Bahrain. The island of Socotra in the Indian Ocean, about 200 miles southeast of the mainland, has strong ethnographic links to Arabia; politically it is part of Yemen.

The peninsula itself has a varying landscape that includes a central plateau, vast deserts, the Hejaz mountain range, and marshy coastal lands. The harsh climate makes it unsuitable for agriculture, however, goat, sheep, and camel herding are common. The Arabian Peninsula, made up of 9 different countries, plays a big part in oil and gas extraction and refining.
