Abu Dhabi is the capital and the second most populated city of the United Arab Emirates (after the Dubai tour). The city of Abu Dhabi is located on an island in the Persian Gulf, off the Central West Coast. Most of the city and the Emirate reside on the mainland connected to the rest of the country. As of 2020, Abu Dhabi's urban area had an estimated population of 1.48 million out of 2.9 million in the emirate of Abu Dhabi, as of 2016.

Abu Dhabi houses local and federal government offices and is the home of the United Arab Emirates Government and the Supreme Petroleum Council. The city is home to the President of the UAE, who is a member of the Al Nahyan family. Abu Dhabi's rapid development and urbanization, coupled with the massive oil and gas reserves and production and relatively high average income, have transformed it into a large, developed metropolis. It is the country's center of politics and industry, and a major culture and commerce center. Abu Dhabi accounts for about two-thirds of the roughly $400 billion UAE economy.
