Qatar,[a] officially the State of Qatar,[b] is a country in West Asia. It occupies the Qatar Peninsula on the northeastern coast of the Arabian Peninsula in the Middle East; it shares its sole land border with Saudi Arabia to the south, with the rest of its territory surrounded by the Persian Gulf. The Gulf of Bahrain, an inlet of the Persian Gulf, separates Qatar from nearby Bahrain. The capital is Doha, home to over 80% of the country's inhabitants, and the land area is mostly made up of flat, low-lying desert.
