Dubai is the most populous city in the United Arab Emirates (UAE) and the capital of the Emirate of Dubai, the most populated of the country's seven emirates

Established in the 18th century as a small fishing village, Dubai grew into a regional trading hub in the early 20th century and grew rapidly in the late 20th and early 21st centuries with a focus on tourism and luxury. It has the second-most five-star hotels in the world and boasts the tallest building in the world, the Burj Khalifa, which is 828 metres (2,717 ft.) tall.

In the eastern Arabian Peninsula, on the coast of the Persian Gulf, it is a major global transport hub for passengers and cargo. Oil revenue helped accelerate the development of the city, which was already a major mercantile hub.

Dubai has been a center for regional and international trade since the early 20th century, and its economy relies on revenues from trade, tourism, aviation, real estate, and financial services. Oil production contributed less than 1 per cent of the emirate's GDP in 2018. The city has a population of around 3.60 million (as of 2022).
