The Burj Khalifa (previously known as Burj Dubai prior to inauguration) is a megatall skyscraper in Dubai, United Arab Emirates. Designed by Skidmore, Owings & Merrill, it is the world's tallest structure, with a total height of 829.8 m (2,722 ft, or just over half a mile) and a roof height (excluding the antenna, but including a 242.6 m spire) of 828 m (2,717 ft). It has also been the tallest building in the world since its topping out in 2009, surpassing Taipei 101, which had held the record since 2004.

Construction of the Burj Khalifa began in 2004; the exterior was completed five years later. The primary structure is reinforced concrete. Some of the structural steel for the building was salvaged from the demolished Palace of the Republic in East Berlin. The building was opened in 2010 as part of a new development called Downtown Dubai. It was designed to be the centrepiece of large-scale, mixed-use development.

The building is named after the former president of the United Arab Emirates (UAE), Sheikh Khalifa bin Zayed Al Nahyan. The United Arab Emirates government provided Dubai with financial support as the developer, Emaar Properties, experienced financial problems during the Great Recession. Then-president of the United Arab Emirates, Khalifa bin Zayed, organised federal financial support. For his support, Mohammad bin Rashid, Ruler of Dubai, changed the name from "Burj Dubai" to "Burj Khalifa" during inauguration.

The design is derived from the Islamic architecture of the region, such as in the Great Mosque of Samarra. The Y-shaped tripartite floor geometry is designed to optimise residential and hotel space. A buttressed central core and wings are used to support the height of the building. The Burj Khalifa's central core houses all vertical transportation except egress stairs within each of the wings. The structure also features a cladding system which is designed to withstand Dubai's hot summer temperatures. It contains a total of 57 elevators and 8 escalators.
