The Arabian Peninsula is a major landmass in Southwest Asia.
The countries typically considered part of the Arabian Peninsula are Saudi Arabia, Yemen, Oman, United Arab Emirates, Qatar, Bahrain, and Kuwait. Jordan is located north of the peninsula and is generally included in the broader Middle East region, often specifically the Levant, but not the Arabian Peninsula itself.
The Arabian Peninsula is bordered by the Red Sea, the Arabian Sea, the Gulf of Oman, and the Persian Gulf. It is the largest peninsula in the world.
